systemd-sysv-generator — Unit generator for SysV init scripts
/usr/lib/systemd/system-generators/systemd-sysv-generator
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 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 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.
SysV runlevels have corresponding systemd targets
(runlevel
). The wrapper unit that is generated
will be wanted by those targets which correspond to runlevels for which the script is enabled.X
.target
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).
