I believe so. This wasn't the case with my problem.

fs rmm didn't work in the cases where I was having trouble.

Yep, and if you name the destination right, it will actually be a mount.
It has the name of the cell and the volume and some other character if
it's a readwrite mount I think.
It's unfortunate though that readlink() doesn't work, as that would make
some find/scan type activities really easy.
