Re: Password to single user boot.

[Ossama Othman <othman@astrosun.tn.cornell.edu>]

Why don't you just restrict booting by using LILO's "password=" and
"restricted" in /etc/lilo.conf? Here is what the man page for "lilo.conf"
says:

       password=password
              Protect the image by a password.

       restricted
              A password is only required to boot  the  image  if
              parameters  are specified on the command line (e.g.
              single).

To prevent modification via a rescue boot floppy you can probably disable
booting via floppy in the BIOS and then password protect the BIOS using
the BIOS's own security features.
