there access GRUB modules in the boot partition. The default location
is /boot/grub/.</para>
<para>The location of the boot partition is a choice of the user that
affects the configuration. One recommendation is to have a separate small
(suggested size is 200 MB) 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 <filename class="directory">/boot</filename> 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 <filename
class="directory">/boot</filename>. If you do this, be sure to update
<filename>/etc/fstab</filename>.</para>
<para>Using the current lfs partition will also work, but configuration
for multiple systems is more difficult.</para>
<para>Using the above information, determine the appropriate
designator for the root partition (or boot partition, if a separate
one is used). For the following example, it is assumed that the root
(or separate boot) partition is <filename
class="partition">sda2</filename>.</para>
<para>For the following example, it is assumed that the root
partition is <filename class="partition">sda3</filename>, and the
seperate boot partition is
<filename class="partition">sda2</filename>. Replace
<replaceable>sda</replaceable> to the name of the device node for your
disk where LFS is being built.</para>
