I'm planning to use "btrfs subvolume snapshot -r <name>" in the system upgrade functionality[1] if the user is using btrfs for their root file system. We've got most of the bits in place already for Fedora 18.
One think that confuses me is the convention for the naming of snapshots. Is there any conventions or prior art there? Can I add metadata to the snapshot so that I don't have encode everything in the snapshot name itself? Also, being able to do a snapshot using a libbtrfs (or whatever) would be much preferable to exec'ing the btrfs command and then trying to parse the exit code and any stderr. I don't know if this kind of thing is the norm for filesystem utilities, but a versioned shared library to use would be awesome. Any advice welcome, thanks.
