Hi Chris,

These are just copy and paste instructions on something I will
do maybe two or three times a year.  I was just thinking that
if "-o uses,exec" let the user write and execute, maybe there was
a "-o" to let the user dismount.

I will just use Substitute User in the copy and paste instructions:
           su root -c "umount /mnt/LIVE"

Thanks to everyone for the tips!

-T
