A better solution would be to move the program part out into a script
in /usr/lib, and have both the init script and service file call out
to that. This wat if the logic changes updates are consistently
delivered to users.

I agree though that this is a quick and good enough solution.

I think it should be added, yes. In practice, it should have little
effect though, otherwise schroot would have bugs filed about this.

As an interested user, thanks for the patch!
