I've just tried this.  It took me a little while to figure out what
was going on since I purposely did not read your description below.

I didn't really "get it" until I read your description.

I don't know if that is a problem or not.  Will there be more words
and descriptions around the entries?  Or, maybe all that is needed
is a "Help" button.

I think it is better to start with pinpoint control like this.

Bleah.  Sounds like another button?  Or maybe an additional dialog
box after the user moves off of this dialog:

"Should non-standard package XXX be upgraded by default in the future?"
Yes/No/Yes to all/No to all

"Should standard package XXX be skipped when checking for upgrades in the future?"
Yes/No/Yes to all/No to all

Hmm.  I think this would be pretty important.  If Chuck Wilson wanted
people to try out a new version of libpng, it might be nice to just
run setup to get that, while keeping everything else the same.

I think this would be a nice feature too.  I'll bet that people would
expect this.
