NAME
       systemd-sysv-generator - Unit generator for SysV init scripts

SYNOPSIS
       /lib/systemd/system-generators/systemd-sysv-generator

DESCRIPTION
       systemd-sysv-generator is a generator that creates wrapper .service units for SysV init[1] scripts in /etc/init.d/* at boot
       and when configuration of the system manager is reloaded. This will allow systemd(1) to support them similarly to native
       units.

       LSB headers[2] in SysV init scripts are interpreted, and the ordering specified in the header is turned into dependencies
       between the generated unit and other units. The LSB facilities "$remote_fs", "$network", "$named", "$portmap", "$time" are
       supported and will be turned into dependencies on specific native systemd targets. See systemd.special(5) for more details.

       SysV runlevels have corresponding systemd targets (runlevelX.target). The wrapper unit that is generated will be wanted by
       those targets which correspond to runlevels for which the script is enabled.

       systemd does not support SysV scripts as part of early boot, so all wrapper units are ordered after basic.target.

       systemd-sysv-generator implements systemd.generator(7).
