When enabled, instructs udisks2 to mount removable drives under `/media/` directory, instead of the
default, ACL-controlled `/run/media/$USER/`. Since `/media/` is not mounted as tmpfs by default, it
requires cleanup to get rid of stale mountpoints; enabling this option will take care of this at boot.
