I've successfully installed FB2 RC2 and I'm currently running some heavy
synthetic testing on it. So far everything has been stable and working
properly. I'll do some real-world testing in the next days to see if it
fails there. If no problems occur I think I'm gonna stick with it, my
fingers crossed. Daily backups are made anyway and the DB doesn't see
frequent updates.

What exactly do you mean with images? The pre-built packages?

I'll keep that as the fallback option. This way I can report any
problems I may find with 2.0.
