- Yes, anyone will be able to get into your system as root by booting
- from floppy (this discussion came up a while ago, and we have some
- very strongly opinionated people as to what should be done :-).

- You have hit upon the only real solution. You either need a BIOS
- which will disallow a floppy boot, or require a password to do it.
-
- The other possibility is a software encryption of the filesystem "on
- the fly"; this is somewhat impractical because it requires some kernel
- modifications and it would considerably slow down performance.
-
- As was pointed out, this is an inherent problem with ANY Unix box (and
- sometimes is useful; for example, I recently had to get in and
- reformat the disk on my Sun because someone had breached system
- security, and booting from tape was the best way to do so).
-
- The "best" solution seems to be going with the password-protected
- BIOS.
