... yeah but that solution totally sucks when you: a) have a lot of data b) need to do this via script c) ??? ... because in a), data will *copied* the slow way, and in b) you leave a bunch of junk laying around in the old root that will rot unless you `rm -rf` it ... and idk about you, but issuing what is very near to that command on someone else's machine -- via script -- makes me REALLY uneasy ;-) i have asked this exact question at least 4 times specifically, and referenced it probably 8-10, in the last 3 years or more. i needed it then. i still need it now. but since i never got an answer up/down or around, i gave up and told people to `rm -rf`themselves ... http://markmail.org/message/7hj5ioqrztkeerqv ... that's from May of 2010, but i don't think it's the first. so, would it possible to implement this, or could someone kindly (and briefly!) explain why it cannot be done? 1. people install stuff to the top-level 2. top-level is unmanageable 3. ^^^^ problem in my case i wrote an initramfs hook that implemented rollback functionality, but there was not way for me to cleanly -- and safely -- "rotate" the user's setup to one that DOES NOT have user items in the top-level volume. -- C Anthony -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
