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

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

DESCRIPTION
       Note: this component is deprecated and scheduled for removal. Please replace remaining SysV init scripts with native
       unit files.

       systemd-sysv-generator is a generator that creates wrapper .service units for System V init[1] scripts in
       /etc/init.d/* at boot and when configuration of the system manager is reloaded. This allows 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(7) for more details.

       Note that compatibility is quite comprehensive but not 100%, for more details see Compatibility with SysV[3].

       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).
