Hi, I've written up a draft of an Fedora 13 feature proposal for filesystem rollback using Btrfs snapshots that are automatically created by yum: https://fedoraproject.org/wiki/Features/SystemRollbackWithBtrfs It'd be great to get feedback on whether this is a good idea, and how the UI interaction should work. We're also discussing it in this fedora-devel thread: http://thread.gmane.org/gmane.linux.redhat.fedora.devel/123695 Some comments I've got already received, from the thread: * People want the UI to allow independent active snapshots per filesystem (i.e. btrfs /home is the live filesystem, and btrfs / is an older snapshot). * Several people think that the ZFS Time Slider patches to nautilus¹ look good, and want that for btrfs. Sounds plausible, but I'm more interested in first working on ways to let developers feel comfortable upgrading to the development version of Fedora each day with the possibility of reverting. * Instead of inventing a new system-config-blah, this should probably be part of Palimpsest². * Perhaps we should encourage people using the Fedora installer with btrfs to create a rootfs separate to their /home, so that they can rollback rootfs snapshots without affecting their homedir.
