Hmm, I normally would be happy to do that, but I am a bit concerned
about the gid=tty parameter. Before we pass that off to the kernel we'd
have to look that up and pass a numeric gid on. But doing NSS queries
from PID 1 is a little bit dangerous. Hence I'd actually prefer if
people apply this in /etc/fstab.

Ideas? Suggestions?
