RFC: Adding a ``user'' mount option

[Jeremy Baggs]

I suppose it would be nice to have something that works "out of the 
box", but the solution I have been using
is group permissions on the devices and then making the mount point in 
fstab relative instead of absolute. ie:

/dev/cd0             cdrom       cd9660   ro,noauto     0   0

Each user has a cdrom directory under their home directory. You still 
need mount points designated for all
possible devices though.   Does anyone know  how  Darwin / OsX are 
handling their auto-mount  magic?
