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
       Incompatibilities 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).
