NAME
systemd-sysv-generator - Unit generator for SysV init scripts
SYNOPSIS
/usr/lib/systemd/system-generators/systemd-sysv-generator
DESCRIPTION
systemd-sysv-generator is a generator that creates wrapper .service
units for SysV init[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.
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. LSB facilities "$remote_fs",
"$network", "$named", "$portmap", "$time" are supported and will be
turned into dependencies on specific native systemd targets. See
systemd.special(5) for more details.
SysV runlevels have corresponding systemd targets (runlevelX.target).
Wrapper unit that is generated will be wanted by those targets which
correspond to runlevels for which the script is enabled.
systemd does not supports SysV scripts as part of early boot, so all
wrapper units are ordered after basic.target.
systemd-sysv-generator implements systemd.generator(7).
