(Repeating myself from another thread where this was somewhat OT)
I updated to F23 using the approved dnf method, with no errors. Now I have an unusable system because /home is not being mounted. It's a btrfs filesystem and when trying to mount it manually I get:
mount: unknown filesystem type 'btrfs'
I have btrfs-progs. This worked correctly on F22. A dnf search shows a storaged-btrfs package which seems to be new (or at least not required in F22) but installing it and rebooting makes no difference.
Booting F22 mounts /home correctly, but I have no desktop as the upgrade removed my working akmod Nvidia stuff and for some reason Nouveau doesn't work.
*Not* a happy camper at this point.
