Yep.  I'm looking at this.

Yes.  The "conflict-resolution" screens are another annoyance.  I'd prefer
it if 'dselect' would wait and give me a single one when I hit <RETURN>.
This is another thing that I've seen turn people away from debian.

Yes I know.  What I should have done is select sendmail first.  As I'd
forgotten to do this, I should have reselected all the packages but there
were about 10 of them and I was feeling impatient ...

I think the right thing to do here is to bring up a screen with:
    "this package provides mail transport (or X)
     which is required for N other packages"

	(A) Cancel
	(B) Select an alternate of packages which provides X:
		(i)  Smail
		(ii) Sendmail
	    and procede to conflict resolution.
	(C) Defer to Conflict resolution (see above).

I'm offering to do this ... :)

Thanks.  This is a useful tidbit.
