The thing one cannot underline enough is that right now you cannot operate on the static, vendor-shipped, read-only data in a single command. But you need exactly that for handling OS snapshots, and for doing proper state-less systems. Why? because taking individual snapshots of /bin, /sbin, /lib/, /lib64, /usr is not atomic, but taking one of /usr alone is. Lennart -- Lennart Poettering - Red Hat, Inc.
