I wholeheartedly agree.
I also agree that wheezy would be the correct moment to do it, and
that we shouldn't wait until wheezy+1.

Considering that most (if not all) scripts would be user custom-scripts,
I'd say that the best way would be to, just move them away on a special
folder, and execute them one by one, without any particular order, and
print a huge warning at boot time, saying:

HEY, we've found crap, please fix! It's there --->

Of course, that's not ideal, but I believe that'd be our best hope to not
destroy *too much* old setups during upgrades. My bet is that most
user-made scripts would not require any dependencies anyway.

Also, doing the last upgrades of some old boxes, I've myself found that
I had some rotten bind 8 init scripts, because bind 8 was removed, but
not purged. That goes on the way to the user (and that annoyed me
quite a bit). I believe that for packages that have been removed but
not purged, it's very very likely that the remaining init.d script isn't
wanted by the user. I'd be for deleting those with a small warning
(or even better, a debconf message with something like: do you want
to delete these antediluvian scripts that are still in your box? yes/no
with yes as default).

Thoughts? Am I doing too many assumptions here, and thinking
too much that everyone is facing the same situation I did?
