I have implemented most of what I was suggesting in the
`feature/shutdown_cleanup` branch. This branch is not meant for 0.12 and
will probably be rebased. I welcome comments on the approach but I do
want to more tests before a formal merge request.

Actually, our boot and shutdown sequences are managed using insserv.
After reading its manpage, I discovered than insserv has an override
mechanism. It looked cleaner to use it instead of blindly use `rm`. This
also meant I could replace the error-prone update-rc.d calls in
the 52-update-rc.d hook by insserv overrides.
