I'm pretty sure Chris was correct.  You system is set up to boot from
the btrfs file system -- not ext4.  Changing the file system will
result in needed changes in boot loader, fstab, etc.

Restoring to an ext4 file system will not result in a bootable system.

How does this sound?

I make a complete tar backup of my system. 

Reinstall F33 to ext4.

Restore that tar, of course fstab and crypttab needs to be corrected. 


Will this work? Does it make any sense?
