Hi again, Capricorny.

Strange you should choose to comment on this old post just now.
I was wondering how to ask you have you done anything with btrfs?
I'm thinking of doing the following:
1. reformat one of my reiserfs 7.2 LiveUSBs with btrfs;
2. see if that works just as well as reiserfs; then
3. try some btrfs snapshot experiments as a replacement for cloop overlays.

Have you already been down this road?
