It is common practice to make another directory under /mnt as the 
actual attach point for mounts. Nothing really prevents you from 
attaching directly to /mnt; it's just not conventional.

You can't umount a mount point "in use" - if there is a file open on 
it, or even if a user is sitting "in" the directory at a bash prompt.
