Then I haven't done a good job at explaining.
One recommendation is to have a separate small partition just for boot
information. That way each build, whether LFS or some commercial distro,
can access the same boot files and access can be made from any booted
system.
If you choose to do this, you will need to mount the separate
partition, move all files in the current /boot directory (e.g. the linux
kernel you just built in the previous section) to the new partition.
You will then need to unmount the partition and remount it as /boot. If
you do this, be sure to update /etc/fstab.
...
cat /boot/grub/grub.cfg EOF
# Begin /boot/grub/grub.cfg
set default=0
set timeout=5
insmod ext2
set root=(hd0,2)
menuentry GNU/Linux, Linux 3.2.11-lfs-SVN-20120314 {
linux /boot/vmlinuz-3.2.11-lfs-SVN-20120314 root=/dev/sda2 ro
}
EOF
If you used a separate /boot partition, remove /boot from the above
linux line. You will also need to change the set root line to point to
the boot partition.
In my case (also with separate /boot partitions) I have a
directory 'boot' on the boot partition (i.e. /boot/boot when
everything is mounted) containing a symlink called 'grub' pointing
to ../grub. I think that I created it (with /boot mounted, so from
the host system) using
mkdir /boot/boot
ln s ../grub /boot/boot
Say what? If you have a separate boot partition mounted on
/mnt/lfs/boot (/boot within chroot) when you run grub-install, then
everything should be installed in the correct location. Those extra
commands should not be needed.
I think this is necessary because grub installed its many
components into /boot/grub and assumes that is where they should be
when it needs them.
Grub looks for grub/ in a couple of places, the first is $root/grub and
then $root/boot/grub where the 'set root' command is used, but not the
'root=' portion of the linux line.
Can you suggest better wording for the book?

If you have a separate boot partition mounted on /mnt/lfs/boot (/boot within chroot) when you run grub-install, then everything should be installed in the correct location. Those extra commands should not be needed. I haven't reinstalled grub since the first version which compiled on x86_64, perhaps 1.97. At that time, either I was in chroot with /boot mounted like that, or else I had used lilo or grub1 to boot the new system - in that case, /boot would have been mounted at /boot directly. Testing bootloaders gives me too much grief (in terms of pre-planning so that I can recover if things go wrong. I remember that it took me a few retries to get it to work, and I'm sure I commented, maybe in lfs-support, at that time. For the other two boxes I've moved to grub2, I just installed the symlink as a matter of course because it worked for me.

The wording is enough to indicate that things might not work as expected, I'm not going to suggest something different unless I get a better grip on the problem.
