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. OBS-URL: https://build.opensuse.org/package/show/Base:System/systemd?expand=0&rev=1258
