+=======================
+
+Generic options:
+
+/etc/sysconfig/authconfig
+
+  used by authconfig to store information about the system's user
+  information and authentication setup; changes made to this file
+  have no effect until the next time authconfig is run
+
+    USEHESIOD=no
+      Whether or not the hesiod naming service is in use.  If not set,
+      authconfig examines the passwd setting in /etc/nsswitch.conf.
+    USELDAP=no
+      Whether or not LDAP is used as a naming service.  If not set,
+      authconfig examines the passwd setting in /etc/nsswitch.conf.
+    USENIS=no
+      Whether or not NIS is in use.  If not set, authconfig examines
+      the passwd setting in /etc/nsswitch.conf.
+
+    USEKERBEROS=no
+      Whether or not Kerberos is in use.  If not set, authconfig examines
+      the settings in /etc/pam.d/system-auth.
+    USELDAPAUTH=no
+      Whether or not LDAP is being used for authentication.  If not set,
+      authconfig examines the settings in /etc/pam.d/system-auth.  Note
+      that this option is separate from USELDAP, and that neither implies
+      the other.
+    USEMD5=no
+      Whether or not MD5-based hashing should be used when setting passwords.
+      If not set, authconfig examines the settings in /etc/pam.d/system-auth.
+      This option affects authentication using both local files and LDAP.
+    USESHADOW=no
+      Whether or not shadow passwords are in use.  If not set, authconfig
+      checks for the existence of /etc/shadow.
+    USESMBAUTH=no
+      Whether or not SMB authentication is in use.  If not set, authconfig
+      examines the settings in /etc/pam.d/system-auth.
+
+/etc/sysconfig/autofsck
+
+  does not normally exist; if it does, it can influence a choice
+  whether or not to fsck after a crash
+
+    AUTOFSCK_DEF_CHECK=no
+      If the user does not respond, choose whether or not to fsck
+    AUTOFSCK_SINGLEUSER=
+      If this is set, drop to single user mode before fsck.
+    
+/etc/sysconfig/init:
+
+  BOOTUP=<some bootup mode>
+     BOOTUP=graphical means use X Windows graphical boot up
+     BOOTUP=color means colorized text mode boot display. 
+     BOOTUP=verbose means old style display
+     Anything else means simplified display, but without color or ANSI-formatting
+  LOGLEVEL=<a number>
+     Sets the initial console logging level for the kernel.
+     The default is 7. 8 means everything (including debugging);
+     1 means nothing except kernel panics. syslogd will override
+     this once it starts.
+  RES_COL=<a number>
+     Column of the screen to start status labels at. Defaults to 60
+  MOVE_TO_COL=<a command>
+     A command to move the cursor to $RES_COL. Defaults to nasty
+     ANSI sequences output by echo -e.
+  SETCOLOR_SUCCESS=<a command>
+     A command to set the color to a color indicating success.
+     Defaults to nasty ANSI sequences output by echo -e setting
+     the color to green.
+  SETCOLOR_FAILURE=<a command>
+     A command to set the color to a color indicating failure.
+     Defaults to nasty ANSI sequences output by echo -e setting
+     the color to red.
+  SETCOLOR_WARNING=<a command>
+     A command to set the color to a color indicating warning.
+     Defaults to nasty ANSI sequences output by echo -e setting
+     the color to yellow.
+  SETCOLOR_NORMAL=<a command>
+     A command to set the color to 'normal'. Defaults to nasty
+     ANSI sequences output by echo -e.
+  PROMPT=yes|no
+     Set to 'yes' to enable the key check for interactive mode as well as
+     asking if a filesystem check should be done. Default is 'no' and
+     the kernel command line option "forcefsck" can be used to check the
+     filesystems and "confirm" can be used to enable interactive startup
+     questions.
+
+  Mageia specific values:
+
+  BRLTTY=yes|no
+       Set to 'no' to disable automatic startup of brltty if it is present
+
+  obsoleted values from earlier releases:
+
+    MAGIC_SYSRQ=yes|no
+       Setting this to 'no' used to disable the magic sysrq key and
+       Stop-A (break on serial console) on SPARC. This setting has been
+       moved into kernel.sysrq and kernel.stop-a settings respectively in
+       sysctl.d/00-system.conf. Setting either of them there to 0 disables
+       it, setting it to 1 enables it.
+    STOP_A=yes|no
+       Setting this to 'no' used to disable the Stop-A (break on
+       serial console) key on SPARC.
+       This setting has been moved into kernel.stop-a setting in
+       sysctl.d/00-system.conf. Setting it there to 0 disables it,
+       setting it to 1 enables it. The setting should be present
+       on SPARC only.
+
+/etc/sysconfig/keyboard:
+
+  KEYTABLE=<keytable file>
+     for example: KEYTABLE="/usr/lib/kbd/keytables/us.map"
+    
+     If you dump a keymap (using 'dumpkeys') to
+	/etc/sysconfig/console/default.kmap
+     it will be loaded on bootup before filesystems are mounted/checked.
+     This could be useful if you need to emergency type the root password.
+     This has to be a dumped keymap, as opposed to copying the shipped
+     keymap files, as the shipped files include other maps from the
+     /usr/lib/kbd/keytables directory.
+     
+  KEYBOARDTYPE=sun|pc
+    on SPARC only, sun means a sun keyboard is attached on /dev/kbd,
+    pc means a PS/2 keyboard is on ps/2 port.
+  
+/etc/sysconfig/system:
+
+	SECURE_TMP=yes|no
+	   Set to 'yes' to have TMPDIR and TMP set to a secure temporary directory
+
+/etc/sysconfig/mouse:
+
+  MOUSETYPE=microsoft|mouseman|mousesystems|ps/2|msbm|logibm|atibm|
+    logitech|mmseries|mmhittab
+  XEMU3=yes|no (emulate three buttons with two buttons whenever
+    necessary, most notably in X)
+  DEVICE=<a device node> (the device of the mouse)
+
+  In addition, /dev/mouse points to the mouse device.
+
+/etc/sysconfig/network:
+
+  NETWORKING=yes|no
+  GATEWAY=<gateway IP>
+  GATEWAYDEV=<gateway device to use, when multiple devices have GATEWAY=> (e.g. eth0)
+  NISDOMAIN=<nis domain name>
+  IFPLUGD_ARGS="<args to pass to ifplugd>" default to "-w -b"
+  NOZEROCONF=
+    Set this to not set a route for dynamic link-local addresses.
+
+  NETWORKDELAY=<delay in seconds>
+    Delay in seconds after all network interfaces are initialized.  Useful if
+    network has spanning tree running and must wait for STP convergence.
+    Default: 20
+
+  DEFAULT_LINK_DETECTION_DELAY=<time in seconds>
+    The default value used for link detection delay if the interface
+    configuration file does not specify it. After this time an interface with
+    missing link beat is considered to be unplugged.
+    Default: 2
+
+  MIN_LINK_DETECTION_DELAY=<delay in seconds>
+    Force minimum link detection delay on all interfaces.
+    Default: 0
+
+  WAIT_UNTIL_REACHABLE=<IP address|DNS name>
+    Network initscript will wait until specified target is reachable.
+    It starts to reaching passed IP address or DNS name every second until it reach it sucessfully or until it reach preset delay NETWORKDELAY (default 30).
+    It works with both IPv4 and IPv6 adress and also with DNS name.
+    Example: WAIT_UNTIL_REACHABLE=8.8.8.8
+    Default: (not set)
+
+  IFDOWN_ON_SHUTDOWN=yes|no
+    If yes, do bring interfaces down during system shutdown. If no, leave them
+    in their current state (this is only supported on hosts using systemd).
+    Default: yes (bring interfaces down)
+
+
+  IPV6FORWARDING=yes|no
+    Enable or disable global forwarding of incoming IPv6 packets 
+    on all interfaces.
+    Note: Actual packet forwarding cannot be controlled per-device, use netfilter6 for such issues
+    Default: no
+
+  IPV6_AUTOCONF=yes|no
+    Sets the default for device-based autoconfiguration.
+    Default: yes if IPV6FORWARDING=no, no if IPV6FORWARDING=yes
+  IPV6_ROUTER=yes|no
+    Sets the default for device-based Host/Router behaviour.
+    Default: yes if IPV6FORWARDING=yes, no if IPV6FORWARDING=no
+  IPV6_AUTOTUNNEL=yes|no
+    Controls automatic IPv6 tunneling.
+    Default: no
+
+  IPV6_DEFAULTGW=<IPv6 address[%interface]> (optional)
+    Add a default route through specified gateway
+    An interface can be specified: required for link-local addresses
+    Examples:
+      IPV6_DEFAULTGW="3ffe:ffff:1234:5678::1"
+        Add default route through 3ffe:ffff:1234:5678::1
+      IPV6_DEFAULTGW="3ffe:ffff:1234:5678::1%eth0"
+        Add default route through 3ffe:ffff:1234:5678::1 and device eth0
+      IPV6_DEFAULTGW="fe80::1%eth0"
+        Add default route through fe80::1 and device eth0
+
+  Note: if IPV6_DEFAULTGW is specified with %interface scope and it
+        doesn't match IPV6_DEFAULTDEV, IPV6_DEFAULTDEV is ignored.
+  Note: it's preferred to use %interface for all addresses, not
+        just link-local if you have multiple IPv6-enabled interfaces.
+
+  IPV6_DEFAULTDEV=<interface> (optional)
+    Add a default route through specified interface without specifying next hop
+    Type of interface will be tested whether this is allowed
+    Examples:
+      IPV6_DEFAULTDEV="eth0" INVALID example!
+      IPV6_DEFAULTDEV="ppp0"
+      IPV6_DEFAULTDEV="sit1"
+    Examples for 6to4
+      IPV6_DEFAULTDEV="tun6to4"
+        Add default route through dedicated 6to4 tunnel device "tun6to4", if configured
+
+  Note: "tun6to4" does not support an additional IPV6_DEFAULTGW.
+        Other interfaces prefer IPV6_DEFAULTGW, if specified.
+
+  IPV6_RADVD_PIDFILE=<pid-file> (optional)
+    Location of PID file for controlling radvd, see IPV6_CONTROL_RADVD
+    Default: "/run/radvd/radvd.pid"
+    Example:
+       IPV6_RADVD_PIDFILE="/some/other/location/radvd.pid"
+  IPV6TO4_RADVD_PIDFILE=<pid-file> (obsolete)
+    As above, still supported for a while for backward compatibility.
+  IPV6_RADVD_TRIGGER_ACTION=startstop|reload|restart|SIGHUP (optional)
+    How to trigger radvd in case of 6to4 or PPP action
+     startstop: radvd starts if interface goes up and stops
+       if interface goes down using initscript call of radvd with related parameter
+     reload|restart: initscript of radvd is called with this parameter
+     SIGHUP: signal HUP is sent to radvd, pidfile must be specified, if not the default
+    Default: SIGHUP
+
+  IPv6 options above can be overridden in interface-specific configuration.
+
+  obsoleted values from earlier releases:
+
+    FORWARD_IPV4=yes|no
+      Create a new file in /etc/sysctl.d/ with the net.ipv4.ip_forward
+      setting instead. Setting it to 1 there enables IP forwarding,
+      setting it to 0 disables it (which is the default for RFC compliance).
+
+    NETWORKWAIT=yes|no
+      This is not used with the move to systemd.
+
+    HOSTNAME=<fqdn by default, but whatever hostname you want>
+      This is now configured in /etc/hostname.
+
+/etc/sysconfig/static-routes-ipv6:
+  Contains lines of the form:
+
+    <device> IPv6-network IPv6-gateway
+    <tunneldevice> IPv6-network
+
+  <device> must be a device name to have the route brought up and
+  down with the device
+
+  For example:
+  
+  eth0   fec0:0:0:2::/64                         fec0:0:0:1:0:0:0:20
+   adds a route for IPv6 network fec0:0:0:2::/64 through fec0:0:0:1:0:0:0:20
+   
+  eth0    2000::/3	                         3ffe:ffff:0:1::1
+   so-called "default" routes for clients
+
+  sit1    2000::/3
+   adds routes through dedicated tunnel interface sit1
+
+  tun6to4  3ffe:ffff:1234::/56			
+   adds routes through hardwired 6to4 tunnel interface tun6to4
+  tun6to4  3ffe:ffff:5678::/56			::5.6.7.8
+   adds routes through hardwired 6to4 tunnel interface tun6to4,
+   specifying next hop   
+
+  Notes:
+    * default routes (such as the "2000::/3" shown above) should be set with
+       IPV6_DEFAULTGW and IPV6_DEFAULTDEV, see more above.
+    * tunnel device "sit0" is not supported here, routes will never be applied
+
+/etc/sysconfig/routed:
+
+  SILENT=yes|no
+  EXPORT_GATEWAY=yes|no
+  
+/etc/sysconfig/rawdevices:
+
+  This is used for setting up raw device to block device mappings.
+  It has the format:
+  	<rawdev> <major> <minor>
+        <rawdev> <blockdev>
+  For example: 
+     /dev/raw/raw1 /dev/sda1
+     /dev/raw/raw2 8 5
+
+/etc/sysconfig/pcmcia:
+
+  PCMCIA=yes|no
+  PCIC=i82365|tcic
+  PCIC_OPTS=<socket driver (i82365 or tcic) timing parameters>
+  CORE_OPTS=<pcmcia_core options>

+  MOUNTPTS='/net /etc/amd.conf'  (standard automount stuff)
+  AMDOPTS=  (extra options for AMD)
+
+/etc/sysconfig/tape:
+
+  DEV=/dev/nst0
+    Tape device.  Use the non-rewinding one for these scripts.
+  
+    For SCSI tapes this is /dev/nst#, where # is the number of the
+    tape drive you want to use.  If you only have one then use
+    nst0.
+ 
+    For IDE tapes you use /dev/ht#, where # is the number of the tape
+    drive you want to use (usually ht0).
+ 
+    For floppy tape drives use /dev/ftape.
+
+  ADMIN=root
+    Person to mail to if the backup fails for any reason
+
+  SLEEP=5
+    Time to sleep between tape operations.  Some drives need a bit
+    more than others, but 5 seems to work for 8mm, 4mm, and DLT
+
+  BLOCKSIZE=32768
+    This worked fine for 8mm, then 4mm, and now DLT.  An optimal
+    setting is probably however much data your drive writes at one
+    time.
+
+  SHORTDATE=$(date +%y:%m:%d:%H:%M)
+    A short date string, used in backup log filenames.
+
+  DAY=$(date +log-%y:%m:%d)
+    This is used for the log file directory.
+
+  DATE=$(date)
+    Regular date string, used in log files.
+
+  LOGROOT=/var/log/backup
+    Root of the logging directory
+
+  LIST=$LOGROOT/incremental-list
+    This is the file name the incremental backup will use to store
+    the incremental list.  It will be $LIST-{some number}.
+

+    For rewinding when done...might not use.
+
+  BACKUPTAB=/etc/backuptab
+    The file in which we keep our list of backup(s) we want to make.
+
+/etc/sysconfig/saslauthd:
+
+  used by the saslauthd init script (part of the cyrus-sasl package) to
+  control which arguments are passed to saslauthd at startup time; changes
+  made to this file have no effect until saslauthd is restarted
+
+  MECH=shadow
+    controls which data source saslauthd will consult when checking user
+    passwords; run 'saslauthd -v' to get a full list of available
+    authentication mechanisms
+  SOCKETDIR=/run/saslauthd
+    controls in which directory saslauthd will be directed to create its
+    listening socket; any change to this value will require a corresponding
+    change in client configuration files
+
+/etc/sysconfig/sendmail:
+  DAEMON=yes|no
+    yes implies -bd (i.e., listen on port 25 for new mail)
+  QUEUE=1h
+    given to sendmail as -q$QUEUE
+    -q option is not given to sendmail if /etc/sysconfig/sendmail
+    exists and QUEUE is empty or undefined.
+
+/etc/locale.conf
+
+  A configutration file for locale settings. See locale.conf(5) for
+  more details. 
+
+  LANG= set locale for all categories, can be any two letter ISO
+    language code
+  LC_CTYPE= locale data configuration for classification and conversion
+    of characters
+  LC_COLLATE= locale data configuration for collation (sort order) of
+    strings
+  LC_MESSAGES= locale data configuration for translation of messages

+
+Files in /etc/sysconfig/network-scripts/
+========================================
+
+/etc/sysconfig/network-scripts/ifup:
+/etc/sysconfig/network-scripts/ifdown:
+
+  Symlinks to /sbin/ifup and /sbin/ifdown, respectively.
+  These are the only two scripts "in" this directory that should
+  be called directly; these two scripts call all the other
+  scripts as needed.  These symlinks are here for legacy purposes --
+  only /sbin/ifup and /sbin/ifdown should currently be used
+  at the user level.
+
+  These scripts take one argument normally: the name of the device
+  (e.g. eth0).  They are called with a second argument of "boot"
+  during the boot sequence so that devices that are not meant to
+  be brought up on boot (ONBOOT=no, see below) can be ignored at
+  that time.
+
+  Also, interfaces may be brought up via the hotplug scripts;
+  in this case, HOTPLUG=no needs to be set to no to avoid this.
+  This is useful e.g. to prevent bonding device activation by merely
+  loading the bonding kernel module.
+
+/etc/sysconfig/network-scripts/init.ipv6-global:
+  Not really a public file.  Contains different basic settings that
+  are set from /etc/[rc.d]/init.d/network at different stages of
+  network initialization.
+
+/etc/sysconfig/network-scripts/network-functions:
+
+  Not really a public file.  Contains functions which the scripts use
+  for bringing interfaces up and down.  In particular, it contains
+  most of the code for handling alternative interface configurations.
+
+/etc/sysconfig/network-scripts/network-functions-ipv6:
+
+  Not really a public file.  Contains functions which the scripts use
+  for bringing IPv6 on interfaces up and down, like addresses, routes,
+  forwarding handling and static or automatic tunneling.
+
+/etc/sysconfig/network-scripts/ifcfg-<interface-name> and
+/etc/sysconfig/network-scripts/ifcfg-<interface-name>:<alias-name>:
+
+  The first defines an interface, and the second contains
+  only the parts of the definition that are different in a
+  "alias" (or alternative) interface.  For example, the
+  network numbers might be different, but everything else
+  might be the same, so only the network numbers would be
+  in the alias file, but all the device information would
+  be in the base ifcfg file.
+
+  The items that can be defined in an ifcfg file depend on the
+  interface type.  The really obvious ones I'm not going to
+  bother to define; you can figure out what "IPADDR" is, I
+  think...  :-)
+
+  Base items:
+    NAME=<friendly name for users to see>
+      Most important for PPP.  Only used in front ends.
+    DEVICE=<name of physical device (except dynamically-allocated PPP
+      devices where it is the "logical name")>
+    IPADDR=
+    NETMASK=
+    GATEWAY=
+    METRIC=
+      Metric for the default route using GATEWAY
+    ONBOOT=yes|no (not valid for alias devices; use ONPARENT)
+    HOTPLUG=yes|no
+    USERCTL=yes|no
+    BOOTPROTO=none|bootp|dhcp
+      'bootp' or 'dhcp' cause a DHCP client to run on the device. Any other
+      value causes any static configuration in the file to be applied.
+    VLAN=yes|no
+    MTU=
+      Default MTU for this device
+    WINDOW=
+      Default window for routes from this device
+    PEERDNS=yes|no
+      modify /etc/resolv.conf if peer uses msdns extension (PPP only) or
+      DNS{1,2} are set, or if using dhclient. default to "yes".
+    DNS{1,2}=<ip address>
+      provide DNS addresses that are dropped into the resolv.conf
+      file if PEERDNS is not set to "no".
+    SCOPE=
+      Set to "scope SCOPE-ID" to set a non-default scope for a statically
+      configured IP address.
+    SRCADDR=
+      use the specified source address for outgoing packets
+    MII_NOT_SUPPORTED=
+      if set don't try to use ifstatus to detect if the link is up.
+    METRIC=
+      if set, assign the route associated with this interface to this
+    metric using ifmetric.
+    HWADDR=
+      ethernet hardware address for this device
+    MACADDR=
+      Set the hardware address for this device to this.
+      Use of this in conjunction with HWADDR= may cause
+      unintended behavior.
+    NOZEROCONF=
+      Set this to not set a route for dynamic link-local addresses
+      over this device.
+    PERSISTENT_DHCLIENT=yes|no|1|0
+      Without this option, or if it is 'no'/'0', and BOOTPROTO=dhcp,
+      dhclient is run for the interface in "one-shot" mode; if the 
+      dhcp server does not respond for a configurable timeout, then
+      dhclient exits and the interface is not brought up - 
+      the '-1' option is given to dhclient.
+      If PERSISTENT_DHCLIENT=yes, then dhclient will keep on trying
+      to contact the dhcp server when it does not respond - no '-1'
+      option is given to dhclient. Note: this disables the automatic
+      checking for the presence of a link before starting dhclient.
+    DHCPRELEASE=yes|no|1|0
+      With this option set to 'yes' (1), when a dhcp configured
+      interface is brought down with 'ifdown', the lease will be
+      released. Otherwise, leases are not released.
+
+    NO_DHCP_HOSTNAME=yes|no|1|0
+      Tells initscripts to not obtain hostname from DHCP server in the ifup-post
+      phase. This option might be useful especially with static configuration of
+      the interface.
+    DHCP_SEND_HOSTNAME=yes|no|1|0
+      Tells initscripts whether the DHCP_HOSTNAME or DHCP_FQDN options (below)
+      should be sent to DHCP server.
+    DHCP_HOSTNAME=<hostname>
+      Sends the specified hostname to the DHCP server.
+    DHCP_FQDN=<fully.qualified.domain.name>
+      Sends the specified FQDN to the DHCP server.
+
+    Please note when both DHCP_HOSTNAME and DHCP_FQDN are specified,
+    only DHCP_FQDN will be used. (Same behaviour as with NetworkManager.)
+
+    DHCLIENT_IGNORE_GATEWAY=yes|no|1|0
+      If set to 'yes', it will cause dhclient-script to ignore any $GATEWAY
+      setting that may be in the ifcfg file for this interface.
+      Otherwise, the dhclient session which obtains an ip-address
+      on the same subnet as $GATEWAY will set the default route
+      to be via $GATEWAY, and no other dhclient session will set
+      the default route.
+    DHCLIENTARGS=
+      Any additional arguments to dhclient.
+    NM_CONTROLLED=yes|no
+      If set to 'no', NetworkManager will ignore this connection/device.
+      Defaults to 'yes'.
+    ZONE=
+      Network zone (trust level) of this connection.
+      If not set, default zone (specified in /etc/firewalld/firewalld.conf)
+      is used. To see all available zones, run 'firewall-cmd --get-zones'.
+    ARPCHECKn=yes|no
+      If set to 'no', ifup will not try to determine, if requested ip address
+      is used by other machine in network.
+      Defaults to 'yes'.
+    ARPUPDATE=yes|no
+      If set to 'no' the neighbours in current network will not be updated with
+      ARP information about this NIC. This is especially handy using LVS Load
+      Balancing with Direct Routing enabled.
+      Defaults to 'yes'.
+    IPV4_FAILURE_FATAL=yes|no
+      If set to yes, ifup-eth will end immediately after ipv4 dhclient fails.
+      Defaults to 'no'.
+
+  For dynamic addressing (BOOTPROTO=dhcp) only DEVICE needs to
+  be set; all the rest will be determined by the boot protocol.
+
+    IPV6_SET_SYSCTLS=yes|no
+      If set, network-scripts will attempt to set sysctls based on the setup
+      of the interface. For example, will try to set `accept_ra` for interfaces
+      where $IPV6_AUTOCONF is set to `yes`. Defaults to `yes`, set to `no` if you
+      want to manage these yourself.
+
+  You can specify which dhcp client to use with the DHCP_CLIENT, if
+  the DHCP_CLIENT is not specified we trying to launch in order :
+      /sbin/dhclient
+      /sbin/dhcpcd
+      /sbin/pump
+      /sbin/dhcpxd
+  if you have a preferred client define the DHCP_CLIENT variable.
+  When you use dhclient (which it is the default on a Mandrake-Linux
+  system) you can specify a timeout of waiting the answer from server,
+  the option is called DHCP_TIMEOUT the default is 60 sec.
+
+  Mageia specific items for DHCP clients:
+    DHCP_HOSTNAME=
+      This option specifies the hostname to request to the DHCP server.
+      The name  may  or  may not  be qualified with the local domain name.
+    NEEDHOSTNAME=yes|no
+      If set to 'yes', set hostname to the host-name option supplied
+      by the DHCP server.
+    PEERDNS=yes|no
+      If set to 'no', do not modify /etc/resolv.conf
+    PEERGATEWAY=yes|no
+      If set to 'no', do not add the gateway provided by DHCP server
+      in the routing table (does not work with dhcpxd).
+    PEERYP=yes|no
+      If set to 'yes', update /etc/yp.conf (specific to dhcpcd)
+    PEERNTPD=yes|no
+      If set to 'yes', update /etc/ntp.conf (specific to dhcpcd)
+    DOMAINNAME=
+      If specified and DHCP_HOSTNAME is not empty, strip DOMAINNAME
+      value in DHCP_HOSTNAME.
+      If empty and dhcpd is used, set the host domainname to the
+      domainname option supplied by DHCP server.
+    DHCP_TIMEOUT=
+      If not empty, this option specifies (in  seconds) for how long
+      the DHCP client will try to get an IP address after its initial request
+      (specific to dhclient and dhcpcd, default is 60 seconds)
+
+  Mageia items:
+    LINK_DETECTION_DELAY=<time in seconds>
+      Delay after which a lack of link beat will be considered to
+      result from an unplugged interface, rather than just down
+
+  Base items being deprecated:
+    NETWORK=<will be calculated automatically with ipcalc>
+    BROADCAST=<will be calculated automatically with ipcalc>
+
+  Alias specific items:
+    ONPARENT=yes|no
+      Whether to bring up the device when the parent device is brought
+      up.

+
+  IPv6-only items for real interfaces:

+      Default: no
+    IPV6ADDR=<IPv6 address>[/<prefix length>]
+      Specify a primary static IPv6 address here
+      Optional, if normal host and a router advertisement daemon is on local link
+      Required, if node is a router and interface should route packets
+      Note: if prefix length is omitted, 64 is assumed
+      Example:
+        IPV6ADDR="3ffe:ffff:0:5::1"
+        IPV6ADDR="3ffe:ffff:0:1::1/128"

+      Enables RFC 3041 IPv6 privacy support if set.
+      Default: RFC 3041 support disabled
+    IPV6_FORCE_ACCEPT_RA=yes|no
+      By default network-scripts will set `accept_ra` only if $IPV6_AUTOCONF is
+      set to `yes`. If you don't want SLAAC addresses but do want to accept RA,
+      then set this to `yes`. Defaults to `no`.
+
+  Special configuration options for multi-homed hosts etc.
+	IPV6_ROUTER=yes|no: Controls IPv6 autoconfiguration
+	IPV6_AUTOCONF=yes|no: Controls IPv6 autoconfiguration
+	 Defaults:
+	  Global IPV6FORWARDING=yes: IPV6_AUTOCONF=no, IPV6_ROUTER=yes

+
+  Optional settings for a 6to4 tunnel

+      Default: no
+    IPV6TO4_RELAY=<IPv4 address> (optional)
+      IPv4 address of the remote 6to4 relay

+      Overwrite local IPv4 address which is accessible from the Internet
+       (optional, in case of static IPv4-NAT behind a router or other special scenarios)
+    IPV6TO4_MTU=<MTU for IPv6> (optional)
+      Controls IPv6 MTU for the 6to4 tunnel
+      Note: Must be greater or equal to 1280

+    IPV6TO4_ROUTING="<device>-<suffix>/<prefix length> ..." (optional)
+      A list of routing tokens to setup proper IPv6 interfaces on the LAN
+      Example:
+         IPV6TO4_ROUTING="eth0-:0004::1/64 eth1-:0005::1/64"
+         Will create one address per eth0 and eth1, taking given SLA
+
+  Optional settings for a 6to4 tunnel or a ppp link
+    IPV6_CONTROL_RADVD=yes|no (optional)

+        IPV6_MTU="1280"
+
+   IPv6-only option to enable DHCPv6 client:
+      DHCPV6C=yes|no
+      This will enable the DHCPv6 client, dhcp6c, to be run for the interface.
+      See man dhcp6c(8) and dhcp6c.conf(5).
+      DHCPV6C_OPTIONS=...
+      This will pass given arguments to the DHCPv6 client.  For example,
+      "-I" option will request network information (e.g., DNS addresses)
+      only, not IPv6 addresses.
+
+  Ethernet-only items:
+    ARP=yes|no (adds 'arp' flag to ip, for use with the
+      ethertap device)
+    LINKDELAY=<time in seconds>
+      Time that the system should pause after the specific interface is
+      enabled.  This may be useful if one interface is connected to a
+      switch which has spanning tree enabled and must wait for STP to
+      converge before the interface should be considered usable.
+    BRIDGE=<br* device>
+      If set, the ethernet device is not assigned an address.  It is added to
+      the specified bridge device instead.
+    EXTRA_ROUTE_OPTS=<string of route options>
+      Extra options to add to the interface route. For example, let's say you
+      wanted an interface route to have an mtu of 1480, but wanted the
+      interface to still have a route of 1500, you could set "mtu 1480" here.
+      Anything here is appended to the `ip route add` or `ip route replace`
+      command.
+
+   Deprecated, but supported:
+    ETHTOOL_OPTS=...
+      Any device-specific options supported by ethtool. For example,
+      if you wanted to force 100Mb full duplex:
+        ETHTOOL_OPTS="speed 100 duplex full autoneg off"
+      Note that changing speed or duplex settings almost always
+      requires disabling autonegotiation with 'autoneg off'.
+
+      Multiple options can also be set like so :
+      ETHTOOL_OPTS="-K ${DEVICE} tso on; -G ${DEVICE} rx 256 tx 256"
+
+      Long term, this should be done by sysadmin-written udev rules.
+
+    No longer supported:
+     PROMISC=yes|no (enable or disable promiscuous mode)
+     ALLMULTI=yes|no (enable or disable all-multicast mode)
+     
+     To properly set these, use the packet socket interface.
+
+  Ethernet 802.1q VLAN items:
+     DEVICE=eth0.42
+       Initscripts use DEV_PLUS_VID_NO_PAD naming mode for VLAN
+       devices.
+               Example: eth0.42 for vlan 42 on device eth0.
+       Valid VLAN ID range is 0-4095. Most ethernet switches reserve
+       VLAN ID 1 to be used as management VLAN; starting from VLAN
+       ID 2 is recommended.
+     REORDER_HDR=yes|no
+       When enabled the VLAN device will move the ethernet header
+       around to make it look exactly like a real ethernet device.
+       This may help programs such as ISC dhcpd which read the raw
+       ethernet packet and make assumptions about the location of
+       bytes. If you don't need it turn it off because there
+       is a small performance penalty. Default is on.
+     GVRP=yes|no
+       When enabled, this will announce new vlan creation to a GVRP
+       enabled trunk port on a switch. Default is off.
+
+  PPP/SLIP items:
+    PERSIST=yes|no
+    MODEMPORT=<device, say /dev/modem>
+    LINESPEED=<speed, say 115200>
+    DEFABORT=yes|no (tells netcfg whether or not to put default
+      abort strings in when creating/editing the chat script and/or
+      dip script for this interface)
+      (meaningless with WVDIALSECT)
+ 
+  PPP-specific items
+    WVDIALSECT=<list of sections from wvdial.conf to use>
+      If this variable is set, then the chat script (if it
+      exists) is ignored, and wvdial is used to open the
+      PPP connection.
+    DEFROUTE=yes|no (set this interface as default route? yes is default)
+    DEBUG=yes|no (defaults to yes)
+      turns on/off pppd and chat (if used) debugging.
+    ESCAPECHARS=yes|no (simplified interface here doesn't let people
+      specify which characters to escape; almost everyone can use
+      asyncmap 00000000 anyway, and they can set PPPOPTIONS to
+      asyncmap foobar if they want to set options perfectly)
+    HARDFLOWCTL=yes|no (yes implies "modem crtscts" options)
+    PPPOPTIONS=<arbitrary option string; is placed last on the
+      command line, so it can override other options like asyncmap
+      that were specified differently>
+    PPPOE_EXTRA = any extra arguments to pass to pppoe 
+    PPPD_EXTRA =  any extra arguments to pass to pppd 
+    PAPNAME=<"name $PAPNAME" on pppd command line> (note that
+      the "remotename" option is always specified as the logical
+      ppp device name, like "ppp0" (which might perhaps be the
+      physical device ppp1 if some other ppp device was brought
+      up earlier...), which makes it easy to manage pap/chap
+      files -- name/password pairs are associated with the
+      logical ppp device name so that they can be managed
+      together.
+    REMIP=<remote ip address, normally unspecified>
+    MTU=
+    MRU=
+    DISCONNECTTIMEOUT=<number of seconds, default currently 5>
+      (time to wait before re-establishing the connection after
+      a successfully-connected session terminates before attempting
+      to establish a new connection.)
+    RETRYTIMEOUT=<number of seconds, default currently 60>
+      (time to wait before re-attempting to establish a connection
+      after a previous attempt fails.)
+    RETRYCONNECT=yes|no (defaults to yes)
+      If this is yes, then we will re-run pppd if it exits with a 
+      "connect script failed" status.  Otherwise, only one attempt
+      is made to bring up the connection.  Note that some connect
+      scripts (for example, wvdial) might do their own retries (such
+      as BUSY or NO DIALTONE conditions).

+  Bonding-specific items
+
+    SLAVE=yes
+      Specifies device as a slave
+    MASTER=bondXX
+      Specifies master device to bind to
+    BONDING_OPTS=
+      A space-separated list of options to the bonding driver for this
+      interface, such as:
+
+      "mode=active-backup arp_interval=60 arp_ip_target=192.168.1.1,192.168.1.2"
+
+  Tunnel-specific items:
+    TYPE=GRE|GRE6|IPIP|IPIP6|EXTERNAL
+      External is a mode for ip6_tunnel interfaces (that cannot be set on
+      the primary ip6tnl0 interface), which permits unwrapping encapsulated
+      packets regardless of their internal IP (v4 or v6) provided the inner
+      address is on the interface. Use $MY_INNER_IPADDR for v4 addresses. Use
+      $IPV6ADDR and $IPV6ADDR_SECONDARIES as usual for v6 addresses.
+    MY_INNER_IPADDR=local IP address of the tunnel interface
+    PEER_OUTER_IPADDR=IP address of the remote tunnel endpoint
+    MY_OUTER_IPADDR=IP address of the local tunnel endpoint
+      If unspecified, an IP address is selected automatically for outgoing
+      tunnel packets, and incoming tunnel packets are accepted on all local
+      IP addresses.
+    PEER_INNER_IPADDR=IP address of the remote end of the tunnel interface
+      If this is specified, a route to PEER_INNER_IPADDR through the tunnel
+      is added automatically.
+    TTL=TTL value for tunnel packets
+      Default is to use the TTL of the packet transported through the tunnel
+
+  Bridge-specific items:
+    TYPE=Bridge
+    STP=off|on (see 'brctl stp')
+    DELAY=forward delay time in seconds (see 'brctl setfd')
+    BRIDGING_OPTS=
+      A space-separated list of bridging options for either the bridge
+      device, or the port device, such as:
+
+      BRIDGING_OPTS="hello_time=200 priority=65535"
+        for bridge devices, or
+      BRIDGING_OPTS="hairpin_mode=1"
+        for port devices.
+
+  TUN/TAP-specific items:
+    OWNER=<owner of the device>
+
+/etc/sysconfig/network-scripts/chat-<interface-name>:
+
+  chat script for PPP or SLIP connection intended to establish
+  the connection.  For SLIP devices, a DIP script is written
+  from the chat script; for PPP devices, the chat script is used
+  directly.
+
+/etc/sysconfig/network-scripts/dip-<interface-name>
+
+  A write-only script created from the chat script by netcfg.
+  Do not modify this.  In the future, this file may disappear
+  by default and created on-the-fly from the chat script if
+  it does not exist.
+
+/etc/sysconfig/network-scripts/ifup-post
+
+  Called when any network device EXCEPT a SLIP device comes
+  up.  Calls /etc/sysconfig/network-scripts/ifup-routes to
+  bring up static routes that depend on that device.  Calls
+  /etc/sysconfig/network-scripts/ifup-aliases to bring up
+  aliases for that device.  Sets the hostname if it is not
+  already set and a hostname can be found for the IP for that
+  device.  Sends SIGIO to any programs that have requested
+  notification of network events.
+
+  Could be extended to fix up nameservice configuration, call
+  arbitrary scripts, etc, as needed.
+
+/etc/sysconfig/network-scripts/ifup-routes
+
+  Set up static routes for a device.
+
+/etc/sysconfig/network-scripts/ifup-aliases
+
+  Bring up aliases for a device.
+
+/etc/sysconfig/network-scripts/ifdhcpc-done
+
+  Called by dhcpcd once dhcp configuration is complete; sets
+  up /etc/resolv.conf from the version dhcpcd dropped in
+  /etc/dhcpc/resolv.conf
+
+/etc/sysconfig/network-scripts/route-<interface-name>
+
+  Contains lines that specify additional routes that should be added when the
+  associated interface is brought up.
+
+  The files are processed by the ifup-routes script and uses the /sbin/ipcalc
+  utility for all network masks and numbers. Routes are specified using the
+  syntax:
+
+    ADDRESSn=<network>
+    NETMASKn=<network/prefix mask>
+    GATEWAYn=<next-hop router/gateway IP address>
+
+  The "n" is expected to be consecutive positive integers starting from 0.
+  For example:
+
+    ADDRESS0=192.168.2.0
+    NETMASK0=255.255.255.0
+    GATEWAY0=192.168.1.1
+
+  adds a network route to the 192.168.2.0 network via the gateway at
+  192.168.1.1. Since you must already have a route to the network of the
+  gateway, there is no need to specify a device.
+
+  Note: The ifup-routes script also supports an older syntax designed to be
+  used directly as an argument to "/sbin/ip route add". This syntax is
+  deprecated, but if no "ADDRESSn" lines are found the following will still
+  work:
+  
+  192.168.2.0/24 dev ppp0
+  
+  adds a network route to the 192.168.2.0 network through ppp0.
+
+/etc/sysconfig/network-scripts/route6-<interface-name>
+
+  Contains lines that are arguments to "/sbin/ip -6 route add"
+  For example:
+
+  site-local route for network fec0:0:0:2::/64
+   via gateway fec0:0:0:1:0:0:0:20 (e.g. on eth0): 
+
+  fec0:0:0:2::/64 via fec0:0:0:1:0:0:0:20
+
+  additional prefix configured to be on-link on eth0:
+
+  3ffe:fffe:1:2::/64 dev eth0
+  
+  6to4 route for network 3ffe:ffff:1::/48, either:
+
+  3ffe:ffff:1::/48
+  3ffe:ffff:1::/48 via ::192.168.1.2
+
+  Note the special case of 6to4 interface: 'via [relay]' is 
+  automatically added if explicit 'via' wasn't specified.
+
+/etc/sysconfig/network-scripts/rule-<interface-name>
+/etc/sysconfig/network-scripts/rule6-<interface-name>
+
+  Contains lines that specify additional routing rules that should be added
+  when the associated interface is brought up.
+
+  Each non-comment line is used directly as an argument to "/sbin/ip rule add"
+  or "/sbin/ip -6 rule add" for rule6 files.
+
