Module paths 

Where the daemon puts its mounts, and what it calls each one.

Mounts go under one root directory, one subdirectory per device, so a file manager or a script can watch a single predictable path and see devices come and go. $XDG_RUNTIME_DIR/mtp is that root: it’s per-user, it’s a tmpfs the session owns, and the OS clears it at logout, so a daemon that dies without cleaning up can’t leave anything behind past the session.
