Thank you for looking at this issue again. :)

This last lintian check have a strange description:

The $all virtual facility is not reserved for local scripts (who came
up with that idea?  It is not from me, who introduced $all to Debian).
And $all is only broken with systemd, as it will ignore the setting.
With sysvinit/startpar/insserv, the value causes scripts to be placed
first/last in the boot/shutdown sequence.  The implementation is
slightly confusing, but it is not totally broken.

The test is good, but as I believe we need a way to scripts to get
started last during boot and first during shutdown, I believe the
proper fix is for systemd to be fixed to implement support for $all
instead of pretending that the feature is useless and reserved for
local scripts.
