Bug#764607: systemd: systemctl does not re-create display-manager.service symlink

[Andrei POPESCU]

Package: systemd
Version: 215-5+b1
Severity: normal

Hi,

# systemctl disable lightdm
Synchronizing state for lightdm.service with sysvinit using update-rc.d...
Executing /usr/sbin/update-rc.d lightdm defaults
Executing /usr/sbin/update-rc.d lightdm disable
insserv: warning: current start runlevel(s) (empty) of script `lightdm' overrides LSB defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (0 1 2 3 4 5 6) of script `lightdm' overrides LSB defaults (0 1 6).
Removed symlink /etc/systemd/system/display-manager.service.
# systemctl enable lightdm

The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
   .wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
   a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
   D-Bus, udev, scripted systemctl call, ...).


I have to run 'dpkg-reconfigure lightdm' to have lightdm's postinst 
recreate the display-manager.service symlink, which is not obvious.


Kind regards,
Andrei
