Internal Program Version: systemd  257.5

This package ships the necessary files that enable minimal SysV and LSB init
scripts support in systemd. It also contains the obsolete SysV init tools
telinit(8) and runlevel(8). You should consider using systemctl(1) instead.

Unless you have a 3rd party application installed on your system that still
relies on such scripts, this package should not be needed at all.

Please note that the content of this package is considered as deprecated.
