I have a similar question but with mount -t pcfs on the Sun- Since it is
mounting a Dos filesystem, and since there is no ownership info on a dos
disk ( and no suid) Is it safe from floppy games (other than rebooting
from the floppy of course)
ie,
execlp("/etc/mount","mount","-t","pcfs","/dev/fd0","/pcfile",(char*)0)
