Another conclusion might be to not give up on the serial console option for remote machines. Should be a reasonable replacement for physical attendance in many cases. Hmm, the option to intstall through a serial console is nice too.

There is more then one way to do it. One can edit /etc/kernel-img.conf. And then to run lilo by hand and probably another one or two manually issued commands. Perhaps lilo -D should be the preferred method. -- "If you have an apple and I have an apple and we exchange apples then you and I will still each have one apple.
