Sirs,

" SUSE " user and fan myself therefore acquainted to the " BTRFS " 
filesystem with its slew of great features such as online defrag, sell-
healing powers and the list goes on.

... That's right, "BTRFS " being your "next-gen" filesystem and no, isn't a 
"beta" file system.

You can get the same deal on let's say "stock OpenSUSE" clean install 
formatted with " BTRFS ". Then you just manage the snapshots with GUI 
app " snapper ".

And listen to this, you will be able to revert the whole shebang ONLINE.

Regards everybody! Fernando.
