    df -h will hide pseudo file systems, including cgroup, leaving only file systems with a size. Note from the man page what all means:

    -a, --all
       include pseudo, duplicate, inaccessible file systems

    Bonus tip: when using util-linux, mount -t xfs,ext4 will print only mounts of that type. Adjust -t option to your desired file systems.

    systemd units, containers, cgroups in general, per user temp directories, and tracing all make use of file systems. While confusing to see an expanding list of non-data file systems, they are useful. Easier to filter them when querying, than to break your system trying to remove file systems.
