NAME         top

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

SYNOPSIS         top

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

DESCRIPTION         top

       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).
