# systemd < v210. This also includes systems migrating from SysV.

|
|
# 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.
