Default mail-transport-agent ( Bug#504880: Disambiguate "installed" for packages)

I think what happens in practice in this case is that apt calls dpkg with
some --force-* flag, or at least that's what the messages that I've seen
scroll by in this sort of situation seem to imply. I agree that it would
be good to have a better way of handling it (although also agree that's a
different bug than this one).

(-cc: the bug. Sorry about that tangent.)

That is a good point, and one that I do not think could not be solved
with triggers. So packages that require an MTA (like fcron) really
need to stop while switching MTAs, or they can find themselves
without a sendmail to talk to (and, in the case of fcron, lose
output from jobs).

Thanks. Will think more.
