Heinrich, you might have hit the nail on the head: I'm using only ZFS on this system. Maybe fatrace thinks zfs doesn't exist, and thus doesn't bother tracing it -- that would explain why the only fatrace output I get on this computer is on squashfs mounts.
A quick test on a Bionic system with mixed ext4 and zfs shows that the ext4 content gets reported and the zfs content does not.
