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 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. 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).
