[Techtalk] Changing the Grub setup

I have a new computer which came with Ubuntu 10.10 installed. I'm very
pleased with it - everything works, and it's a heck of a lot faster than
my old computer, which is 10 years old.
The root filesystem is on /dev/sda2 and the /home partition
/dev/sda1 is a boot partition, and is not mounted once the system is up
and running. It contains a /boot/grub/menu.lst file which reads:
timeout = 5
default = saved
title Ubuntu 10.10 (Maverick Meerkat)
title Upgrade/ Spare partition (currently unused)
The root filesystem on /dev/sda2 has a /boot/grub/grub.cfg file which
contains all the stuff from /etc/grub.d/ . I have not come across this
newer version of Grub before, and I'm finding it hard to get my head
When I boot the computer, I see the simple Grub menu provided by the
file on hd0,0 (/dev/sda1). This then presumably boots the computer
according to the grub.cfg file on /dev/sda2, although I don't actually
see that menu. Certainly, though, the file gives me what I would
expect and am used to - e.g. the latest version of the kernel plus the
previous one, with recovery mode and memory test options.
Is there any advantage in having things set up this way? I would prefer
to see the actual menu which is currently on /dev/sda2 . Could, and
should I simply transfer the /boot directory from /dev/sda2
to /dev/sda1, replacing the one that's there? Or how do I build the
thing properly in that location, if it's a good idea?
I haven't encountered this latest version of Grub before, and even the
old version used to scare me a bit - there's always the prospect of
making the computer unbootable!
Any observations and advice will be gratefully received.
