- Doing so would be a BIG security hole. An ordinary user could mount a
- floppy with a setuid-root shell, for example. Running the shell would
- be the same as having a ``su'' command with no password.

- Of course, if users already have access to the machine, and to drive
- a:, they can just boot from their own floppy, so the security problem
- is there no matter what you do.
