It's not the preferred way of installing, you are correct.  The majority 
of packages that are on the two DVD set, that aren't in the Install DVD, 
aren't listed in the comps entry, and thus, you cannot actually install 
them during the install.

OK, it just occurred to me that both of you were talking about doing 
"upgrades" and not "installs".  Are you upgrading from SL 6.0 to SL 6.1?
If that is the case, it is possible that you might have some packages 
installed from SL 6.0 that aren't on the Install DVD.

The 2 DVD set has caused us more problems than it's solved.  (In my 
opinion)

I'm thinking for SL 6.2, we either won't have the Everything DVD, or 
make it a Dual Layer DVD iso.  I'm leaning towards the Dual-Layer DVD, 
because there are several people/groups who need the Everything DVD's to 
easily bring the whole repository to a non-networked machine or cluster.
