Hi! Sorry, I was wrong thinking about booting from snapshot... So now, will be possible with btrfs scenario like this: - make (writable?) snapshots of whole system (all filesystems) before dangerous things - do what we want (upgrade, install new software...) - then "apply" these changes and remove those snapshots or "rollback" changes by (re)booting, mounting snapshots and discarding changes since these snapshots.
Or even: - explicitly start transaction(s) on filesystem(s) with userspace tool (btrfsctl) - do what we want - commit or rollback transaction (like in RDBMS) Thanks! _______________________________________________ Btrfs-devel mailing list [email protected] http://oss.oracle.com/mailman/listinfo/btrfs-devel
