I have a few times, but the instructions given in UPDATING don't give me an
indication of /how/ I should be answering these questions posed by pkgdb
-Ff (or Fu, or whatever). For example, it's not clear to me /why/ we're
uninstalling certain packages before the upgrade - are they obsolete or is
it an order dependency? Later during the process with things are fubar, I
don't know whether installing certain stale dependencies are correct or not
nor do I know how to answer questions about package origins.
I'd love to help myself here, but having some cluepons would help.
