suid programs are not the only problem with allowing users to mount floppies,
what is going to stop me from putting my floppy in the drive and saying
mount /dev/floppy /etc

now i have mounted a floppy as /etc...  what happens if i have a passwd file
on my floppy with a no password root account??  This is the exact procedure
i used to circumvent hewlett packard's PAM on the integral pc.   it allows
anyone to mount floppies...
