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.
