I  have tested adding some loopback mounts of files on the root filesystem;
umountfs was able to unmount them without any problem.

We know that there _are_ issues with loopback filesystems, though:
#49670, #138040, #288106.

Hmm, yes, that might be better than what we do now.  It adds a bit of complexity,
