Just for the Google record, someone mailed me privately (apparently something went wrong with getting mail sent to the list) to point out that this lack of an upgrade path between RHEL versions was a one-time thing for one specific RHEL version transition, and RHEL does indeed support in-place upgrades for support customers for subsequent releases (and has tools and whatnot to help determine if anything will break). -- Russ Allbery (r...@debian.org) <http://www.eyrie.org/~eagle/>
