Re: upgrading from rh7.2 to 7.3 -- dependency problem

functionality that moves around is really difficult to deal with.  If a
package name changes or the dependance in the package is written
slightly differently so that the upgrade dependancies and the installed
dependancies dont match up perfectly...its hard for an algorithm to
really know what to do...so its safer and best to just warn the user and
let them do what they need to do by hand.

Upgrading between distro versions usually breaks a lot of the logical
rules in package development...the upgrade via the redhat iso's usually
forces a lot of things to downgrade/upgrade or remove things to get the
versions of packages installed on the cd.

I really like grab's client-side dep resolution...and there is room for
improvement. But I can't think of an algorithm to suggest to greg to
parse the oddball cases better.
