that's a tough one... if you think about it, you needed root privileges
to issue the telinit 1 or boot from LILO (well not root, but physical
access trumps root any day) in the first place, Single-user mode is
password-less on every Unix I've ever met (FreeBSD, OpenBSD IIRC,
Solaris, about twenty Linuces). Since you may be there to deal with a
missing or corrupt /etc/passwd & /etc/shadow, not asking for the
password is the difference between requiring a rescue disk and not.

I think the best you can do is to set a BIOS password, a LILO password,
and/or to encrypt the partition.
