[New: openFATE 319287] require systemd-machines subvolume creation at install time

Feature added by: Chris Murphy (cmurf) Feature #319287, revision 1 Title: require systemd-machines subvolume creation at install time Requested by: Chris Murphy (cmurf) Partner organization: openSUSE.org Description: On Btrfs, create a systemd-machines subvolume in the top level of the file system, and add it to fstab to mount at /var/lib/machines. Without this, any rollback will be missing nspawn containers, because systemd-nspawn now creates Btrfs subvolumes inside /var/lib/machines/ as backing to manage containers. http://lists.opensuse.org/opensuse-factory/2015-07/msg00525.html -- openSUSE Feature: https://features.opensuse.org/319287
