SYSTEMD-SYSV-GENERATOR(8)               SYSTEMD-SYSV-GENERATOR(8)

     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 m[blue]SysV initm[][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.

          m[blue]LSB headersm[][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.

          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).
