SYSTEMD-SYSV-GENERATOR(8)systemd-sysv-generatorSYSTEMD-SYSV-GENERATOR(8)
systemd-sysv-generator - Unit generator for SysV init scripts
/usr/lib/systemd/system-generators/systemd-sysv-generator
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
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).
