This could be done somewhat safely with BTRFS or LVM. Make /usr read-only. Create a read-write snapshot of /usr, apply the updates to that snapshot and then somehow atomically replace /usr with the new snapshot. Just mount over it? Is there a way to unmount the old /usr after, or would this plan just result in an eventual pile of 100 copies of /usr?

Snapshotting can help, but btrfs still seems not ready for production, and LVM snapshots are quite buggy - see http://serverfault.com/questions/279571/lvm-dangers-and-c...
