Bug#851730: init-system-helpers: update-rc.d fails to disable nbd-server

[Christoph Anton Mitterer]

Package: init-system-helpers
Version: 1.46
Severity: important

Hi.

Not sure why the following happens:
# update-rc.d nbd-server disable
update-rc.d: error: nbd-server Default-Start contains no runlevels, aborting.


Trying to enable it gives the same error:
# update-rc.d nbd-server enable
update-rc.d: error: nbd-server Default-Start contains no runlevels, aborting.


# grep Default-Start /etc/init.d/nbd-server
# Default-Start: 2 3 4 5 


# l /etc/rc*.d | grep nbd

Thus one cannot cleanly disable this and systemd always starts it again.

Marking it important as this may lead to devices being exported while the user
thinks the daemon was disabled.


Cheers,
Chris.
