> The switch to Btrfs will use a single-partition disk layout, and Btrfs’ built-in volume management. The previous default layout placed constraints on disk usage that can be a difficult adjustment for novice users. Btrfs solves this problem by avoiding it. good call, subvolumes came to the rescue of the /home partitioning. It's useful, but the inflexibility was in the proper split of available disk space. Novice users then saw warnings for /home - when there was still plenty of space on the root partition.
