I believe I have used systems like that but I can't for the life of
me remember what it was. I thing the option was "user" and it meant a
user could do the mount or umount, but only with the arguments specified
in the fstab.

I tend to agree with putting things like this in user land if possible.
It is certainly more flexible. I just thought that the kernel restriction
could be relaxed a bit with no detriment. But then I forgot about the 't'
bit ;-(.

For reference, a quick experiment on linux shows that permission is
denied if the 't' bit is set.
