Now where would he get that idea from?

chips-computer:~ chip$ uname # show that this is Darwin (Mac OS X)
Darwin
chips-computer:~ chip$ ls -ld / # show permissions of root directory
drwxr-xr-x  39 root  admin  1394 Nov 15 09:00 /
chips-computer:~ chip$ mkdir /a # try to create something in /
mkdir: /a: Permission denied
