Package: mate-system-monitor Version: 1.18.1-1 Severity: normal It appears that mate system monitor filters out zfs file systems from file system usage tab. I only see vfat and ext4, but no other file systems (zfs, tmpfs, pstore, cgroup, efivarfs, autofs, debugfs, rpc_pipefs, mqueue, binfmt_misc) that I see in mount.
When looking at df -h -T, I see devtmpfs, tmpfs, ext4, zfs, vfat without problems. df by default filters out psuedo file systems. It might be worth looking into how df is detecting them, and use the same logic in mate system monitor.
