Bug Description
Brief Description
-----------------
It appears that a single "mount" operation on a single file system (including a "mount -o remount") makes systemd send 2 PropertiesChanged message per mount point seen on the system (even if the mount point is not touched).
This creates a huge systemd load, and potentially a huge load on DBus.
This is a known issue:
