That's a good side-effect too ;-) -- the original reasoning, dating
back to when Wad was working on the xs, was about
resizing/mirroring/striping the /library partition.

With LVM it's possible, but not pretty. If btrfs does deliver on the
out-of-this-world expectations everyone has on it... it'll mean that
separating the OS and data is a clear win.

On the OS side, we can use checkpoints for rpm-driven upgrades (so we
can rollback in case of trouble).

On the /library side, mirroring and striping become much more doable, and sane.

cheers,
