The prompt is printed by the MBR that is installed as part of the mbr
Debian package (or by the boot floppies). If you install LILO in the
MBR (using boot=/dev/hda instead of boot=/dev/hda1) you wont see this
prompt, because you overwrote the code that produced it.
See /usr/share/doc/mbr/README on what the prompt means and why it is
different on different machines.
I do agree, however, that it is not a security hole. If someone wants
to make the console secure, they would have to modify lilo.conf
anyway, and so could change the boot= line as well.
