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].

       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).
