IMO, it is all working as it is supposed to. As for Sarge, I wouldn't know
because I never used Sarge. My first Debian was Etch, and it didn't last
long because I am the sort that prefers the bleeding edge.
Remember that Knoppix is based on Sid/Experimental, so of course the grub that
it uses is much newer than that of Sarge, and depending on which version of
Knoppix one uses, could be newer than that in Etch.
I would strongly recommend just converting your Sarge system to Etch, but I
can understand your reluctance to do so. But, like I said before, once the
MBR is written, then just adjust grub's menu.lst file and have it boot any
system you want. If you add new systems, you don't *have* to let the
installation install grub, since it's already there, but you would have to
tell your menu.lst where to fine the new system. That is just another Title
entry into the grub's menu.lst
Best of luck to you. I think you're getting the hang of the grub commands.
