These symlinks are here for legacy purposes + only -- they'll will probably be removed in future versions, so + only /sbin/ifup and /sbin/ifdown should currently be used. + + 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. + +/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 + and interface change notification through netreport. + +/etc/sysconfig/network-scripts/ifcfg-<interface-name> and +/etc/sysconfig/network-scripts/ifcfg-<interface-name>-<clone-name>: + + The first defines an interface, and the second contains + only the parts of the definition that are different in a + "clone" (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 clone 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.
