Franck Bui b340d1e22d - Fix the default target when it's been incorrectly set to one of the runlevel
targets (bsc#1196567)
  The script 'upgrade-from-pre-210.sh' used to initialize the default target
  during migration from sysvinit to systemd. However it created symlinks to
  runlevel targets, which are deprecated and might be missing when
  systemd-sysvcompat package is not installed. If such symlinks are found the
  script now renames them to point to 'true' systemd target units.
- When migrating from sysvinit to systemd (it probably won't happen anymore),
  let's use the default systemd target, which is the graphical.target one. In
  most cases it will do the right thing anyway.

# All hacks can potentially break the admin settings since they work in /etc...

# During migration from sysvinit to systemd, we used to set the systemd default
# target to one of the 'runlevel*.target' after reading the default runlevel
# from /etc/inittab. We don't do that anymore because in most cases using the
# graphical.target target, which is the default, will do the right
# thing. Moreover the runlevel targets are considered as deprecated, so we
# convert them into "true" systemd targets instead here.
