Once question, are we looking at using a layout like openSUSE is
doing? ( https://en.opensuse.org/SDB:BTRFS ) utilizing subvolumes, or
are we looking at something like
/boot/efi > EFI (FAT32)
/ > btrfs
BTW that layout.
Anaconda still does not allow installing something like that because it does not allow /boot on btrfs (technically there is no any reasons to demand that and /boot can be just subvolume on the root btrfs pool).
