I don't know anything about Fedora/packages/etc., but wanted to say--as
soon as possible--that as long as grape (running -fixes) is your backend
and tomato (running trunk) is the frontend, you're in pretty good shape
(as long as you don't tell the trunk machine to upgrade the DB schema).
If, instead, grape (running -fixes) is your frontend and tomato (running
trunk) is the backend, you should keep around that backup you made
before the upgrade because it's your only path back to -fixes. I'd
recommend getting the backend on fixes as quickly as possible (however
you end up doing that) and restoring the pre-update (the -fixes) backup
and "losing" all the shows you recorded between the backup and the fix
(you can always put those interim shows into MythVideo to watch or even
use something like myth.rebuilddatabase.pl to import them into MythTV).
Good luck with the rest.
