# This script is called by "systemctl enable/disable" when the given unit is a
|
|
# SysV init.d script. It needs to call the distribution's mechanism for
|
|
# enabling/disabling those, such as chkconfig, update-rc.d, or similar. This can
|
|
# optionally take a --root argument for enabling a SysV init script in a chroot
|
|
# or similar.
|
|
#
|
|
# chkconfig(8) and insserv(8) are no more available hence let's do the bare
|
|
# minimum and create/remove the symlinks for the well known runlevels and
|
|
# nothing more. Note that we don't take care of enabling/disabling the service
|
|
# dependencies as the sysv-generator will take care of them for us (openSUSE
|
|
# specific).
