Yeah, it's still on the TODO list. The autofs protocol for doing this
is horrid, but Kay managed to figure out how it works, a terse
description for it is in the TODO list, but so far nobody actually sat
down and wrote the code for it. Doing this probably involved adding
some threads in PID 1, due to blocking ioctls, which is nasty, but I
guess OK, but makes this not the sexiest thing to hack on...

Anyway, would be happy to take a patch for this!
