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.
