Hello,
as I already described before, my prefered solution to the problem
is the use of a kind of variables in GRUB like
$MEM, $IP, $SERVER_IP, etc, etc,...
So the user can decide himeself using kernel paramters, like
kernel /boot/vmlinuz mem=$MEM root=/dev/hda2
etc.... If there is enough information, also things like NFSROOT
and IP configuration can be setup.
These variables ('$MEM', etc..) should be usable in all builtin
command.
This varibles cannot be used to do calculations (like $MEM-20) as
we hove *NO* shell script language here. It should only do a
replacing in the command line.
Cheers
