- For whatever it's worth as a non-developer, I really like this. I think it's good to get some btrfs stuff implemented now so that Fedora is ready to fully utilize it whenever it's marked stable.
- You mentioned that it would rollback user's home directories if they were btrfs as well. I have two questions about that. One, would it be possible/practical to default to a seperate /home volume for btrfs installations and, two, if it's on a seperate partition, but is also btrfs, would it still roll-back? IMO, it should be implemented so that it doesn't, but your feature proposal makes it sound like it would. - eqisow
Thanks for the comment. I was trying to keep things simple by having a single choice of snapshot name that would apply across all btrfs filesystems -- it would be easier not to have to present a matrix of each filesystem and the snapshot that should be active on it -- but I suspect you're right that the matrix is the right way to go.
Not sure about defaulting to a separate /home; I think that if someone chooses btrfs they're already way into specifying the disk setup completely manually. Worth thinking about, though.

- There has been UI work on ZFS in OpenSolaris, we may like reuse it
- Moreover I was interested in contributing some time on nautilus patch for slider.

Cool. The Time Slider work looks exciting, I'm just wanting to take small steps and start out with whole-fs rollbacks. If you want to go for it, I think you should. :)

- We could make a subvolume for /home, in order to avoid the problem relative to having different partition for / and /home. Snapshotting is not recursive throught volumes, so personal datas remain untracked. Also, we could use a snapshot-directory (for example /snap), and set it as a subvolume, to avoid to have a fs tree like: /snap3/snap2/snap1 (and similar paths).
- So, there are many possibility to make it flexible for this feature proposal :)

That's an interesting idea, thanks. I don't think we can mandate any particular partition layout, but we can certainly recommend one that we think works best.
