File of Package systemd-v237-testsuite

# This script is supposed to be executed from the %post section. It
# contains all hacks needed to update a system which was running
# systemd < v210. This also includes systems migrating from SysV.
# All hacks can potentially break the admin settings since they work
# in /etc...

# Try to read default runlevel from the old inittab if it exists. If
# it fails fallback to runlevel 3 which should still be better than
# the rescue shell.
# Note: /etc/inittab was part of the aaa_base package which can be
# upgraded before systemd is. Therefore this file is likely to be
# missing.
