The problem with kubic was the unknown space it was in - was it an appliance, or a generic distro with kubernetes packages. The btrfs stuff could have been quite good if they shipped btrfs snapshots as the update mechanism (like coreOS), but there was the pressure from the SLES/openSUSE side to let deployers install random software as needed, which meant you were left with the mess of "zyyper dup" + snapshot + reboot, and not having a known version for doing config updates.

The team behind is really smart, and doing good work - it just needed a forceful vision imposed on it for it to go somewhere.
