I wonder what it means for SuSE Enterprise Linux in the long run.

Are they going to migrate SLE to be bug-for-bug RHEL compatible but keep their own tools on top? What about OpenSUSE? I'm an avid SLE/OpenSUSE user and it was chosen specifically because it's not an RHEL clone.

SuSE uses btrfs for the root filesystem, and although this can be quite dangerous if it fills up, it does allow much greater flexibility in rolling back the OS to a working state.

It would be interesting if this capability returned to OpenELA. It could be done with rhel7 (and clones).

There are likely some users who consider this a must-have.

I can guarantee you that SuSE will only ever support btrfs with their own kernel. There are a ton of fixes backported in theirs. At which point you are running SLES anyway.

Oracle's UEK also has btrfs support, and I use it. It is designed to be installed over rhel.

A further collaboration on an OpenELA btrfs-enabled kernel incorporating both SuSE and Oracle requirements will easily supplant stock rhel.

For one thing, the UEK returns support for a large array of hardware that has been removed from stock. This list is very large.
