f22 fedup with btrfs snapshot?

[Neal Becker]

I have f21 installed on btrfs.  I wonder what's a good procedure to use 
fedup along with btrfs snapshot, so that I can backout to f21 if I don't 
like it?

Right now I have:

 sudo btrfs sub list /
ID 257 gen 67442 top level 5 path root
ID 318 gen 67442 top level 5 path home

-- /etc/fstab
UUID=93c586fa-6d86-4148-a528-e61e644db0c8 /                       btrfs   
subvol=root     0 0
UUID=93c586fa-6d86-4148-a528-e61e644db0c8 /home                   btrfs   
subvol=home     0 0
UUID=e907e423-4282-4ca9-a873-b544d17d34b9 /boot                   ext4    
defaults        1 2
UUID=b0cde31d-3694-4b98-ad90-e28c7d35a869 swap                    swap    
defaults        0 0
