I can think of few ways to revert changes with btrfs, but I wonder what are the trade-offs between each method and perhaps there is already research done on this?
ways to restore a snapshot ( post kernel 3.* ): a) via set-default 1. btrfs subvolume set-default / $id 2. reboot b) always mount into snapshot 1. mount -o suvol=/.current $disk # at initrd 2. btrfs subvol del /.current 3. btrfs subvol snapshot /.snapshotA /.current 4. reboot c) rsync 1. rsync $options /.snapshotA /.current 2. reboot - Vytas Dauksa -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
