I've long wanted to help with fedora rawhide a bit more but only really 
have it on the one computer I work on. So this would make it possible 
for me to do that. I think that's great.

I have a few questions. Suppose I do an update, and it breaks X or some 
other important piece for me. I reboot into my previous snapshot. From 
there I continue to work.

Do I have to remove the 'future' snapshot I came back from to continue 
working in that snapshot? Or is that just best practice. If I move 
forward, I'd have to move all the work I did in that snapshot to the 
head/snapshot that just got fixed with an update...

Just thinking out loud here.
