- 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.
