That is not all.
Device files must also be ignored.
What if I use my Amiga3000UX at home and create a floppy with a
device file that has the device numbers of /dev/kmem, and then make it 777.
(It would be in my uid and not suid). Now I have a way to alter and/or poke
throught kernel memory no?
So device files must also be ignored.
