The other option is to use sudo instead of su -c because with sudo you can give the user only permission to run the exact command as root. Further more you can configure it to prompt the user for their own password on just to let them run it without a password

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!
