That would allow all users to mount *anything*, which is not what I want. I 
want any user to mount the thumb drive, but I certainly don't want any user 
but root to mount the hard disk. Linux doesn't have vfs.usermount; 
instead /bin/mount is suid root and checks whether the device and mount point 
are listed in /etc/fstab as user-mountable.

What I actually did (I had a visitor who brought a thumb drive) was mount it 
as root and then copy files.
