10
12 systemd-sysv-generator is a generator that creates wrapper .service
13 units for SysV init[1] scripts in /etc/init.d/* at boot and when
14 configuration of the system manager is reloaded. This will allow
15 systemd(1) to support them similarly to native units.
16
17 LSB headers[2] in SysV init scripts are interpreted, and the ordering
18 specified in the header is turned into dependencies between the
19 generated unit and other units. LSB facilities "$remote_fs",
20 "$network", "$named", "$portmap", "$time" are supported and will be
21 turned into dependencies on specific native systemd targets. See
22 systemd.special(5) for more details.
23
24 SysV runlevels have corresponding systemd targets (runlevelX.target).
25 Wrapper unit that is generated will be wanted by those targets which
26 correspond to runlevels for which the script is enabled.
27
28 systemd does not supports SysV scripts as part of early boot, so all
29 wrapper units are ordered after basic.target.

31 systemd-sysv-generator implements systemd.generator(7).
