(not an exhaustive list)
1: "Disk Space Full Because of Snapper" on https://en.opensuse.org/SDB:BTRFS
2: Since 2015, BTRFS has been the default / filesystem on openSUSE, which
recommends minimum / filesystem size of 20GB for EXT4, compared to 40GB for BTRFS.
3: Much more common / filesystem freespace exhausted threads on mailing lists and
web forums from BTRFS users compared to EXT4 users, with the usual recommendation
to delete one or more snapshots to free space.
