Let me see if I understand grub's interpretation of menu.lst correctly.
I have a boot stanza in my menu.lst:
title Debian GNU/Linux, kernel 3.0.0-1-686-pae testing (squeeze-grub) OK
root (hd0,5)
kernel /vmlinuz-3.0.0-1-686-pae root=/dev/mapper/VG1-testing--root ro
initrd /initrd.img-3.0.0-1-686-pae
this means that the kernel, /vmlinuz-3.0.0-1-686-pae, is taken from the
top-level directory on partition (hd0, 5) which what used to be called /dev/sda6,
and that when this kernel is booted, it will use /dev/mapper/VG1-testing--root
as its root partition. It's the /etc/fstab file within
/dev/mapper/VG1-testing--root that it will use to find out what to
mount on /boot, which should properly be the same (hd0, 5) that was
used to find the kernel.
And finally, when grub-update is run, it uses some of the options within
menu.lst when it creates the new one. Here I mean options other than
just the existing hand-made static boot stanzas.
