ifup-post: always update nameserver & search entries in /etc/resolv.conf

2017-10-31T12:11:59+00:00

  This is complete rework of how we generate the /etc/resolv.conf.

  Fixes:
   * always update 'nameserver' & 'search' entries when DNS* & DOMAIN
     options (respectively) were updated in ifcfg-* files
   * always update the order of 'nameserver' entries when the order of
     DNS* options was updated
   * always keep /etc/resolv.conf.save as a proper backup - do not
     overwrite it everytime when updating 'nameserver' or 'search'

  Enhancements:
   * added support for DNS3 option (equals to MAXNS value in GLIBC)
   * added logic to process duplicate DNS* options
   * added logic to process randomly omitted DNS* options (e.g. omitting
     DNS1 while specifying DNS2 and/or DNS3 will still work now)

  This work was based on these two RHEL-7.5 BZs:

'debugmode' subpackage dropped completely

2017-10-16T17:04:09+00:00

  Using this package was very dangerous, and could lead to instability
  of system, or even being unable to bootup at all, and value of this
  functionality was at least questionable, and was not documented.

  We decided to drop functionality completely, to make sure users do not
  install it accidentally (e.g. by using globbing with 'dnf install').

  Resolves: #69

sysconfig/init* files dropped

2017-10-16T13:18:40+00:00

  Users can still create the /etc/sysconfig/init file manually to
  override the default values, which are now taken from init.d/functions.
