*blink* *blink* That should _totally_ not matter. If it does, it's a
bug. (You didn't say what "does not work" means in this context, lemme
see what I can dig up...)

That would be a bug. The fact that remount doesn't work without an
absolute path is _also_ a bug. Hmmm...

(I haven't put together a proper mount test suite yet because it
requires root access and a known host environment, meaning it's gated by
a dependency on a qemu-based test environment, which is gated on my
taking my aboriginal linux project apart and putting it back together
again as described on that list. Working on it. But mostly I have to get
back to Austin and a decent work environment again so my development
bandwidth for these projects isn't so severely constrained...)
