I agree completely and my scripts have been doing it that way
since forever. I really never bother to look at the book for
this part of the build as my scripts have everything in it I
need. In fact I create a README file, just to have info handy:
cat > /boot/grub/README << "EOF"
Edit the menu.lst file to set up the various boots you may have
on the machine.
Then run the "grub" program.
At the grub prompt, use the following commands:
root (hd0,3) # This tells grub where to find the staging files
setup (hd0) # This is where grub will write the MBR
Grub's nomenclature is different than Linux or Lilo. Grub starts
numbering the hard drives at 0 and partitions at 0.
Grub also skips cdroms and only lables hard disks. So, if Hard
Disk A was the first device on IDE1 and a cdrom was the second
device on IDE1, the first hard disk at IDE2 would be hd1.
Hopefully, someone else will comment and we'll open a ticket
