If you search the archives, you'll find that we've done quite a bit of
research to find out what it'd take to get rpm to reasonable
reliability (or recoverability) in the face of powerloss, which is the
core promise of olpc-update.

On ext2/3/4, jffs2, ubifs and similar traditional FSs - impossible.

On btrfs (and similar modern FSs with straightforward snapshotting) -
doable. You may find that cjb has worked on a nifty yum plugin.

As btrfs matures, and if there aren't other holdups, we are likely to
use it on the platforms where we can.

thanks,
