The man pages for the Btrfs tools and for the XFS ones explicitly says that
fs_passno should be set to 0 for both. So, excluding network filesystems and
any filesystem formatted as Btrfs or XFS... that basically leave us with a
value of 1 only for root ext2/3/4 filesystems. That's what I implemented and
tested here (waiting for code review):
