<para>[bdubbs] Upgraded to GRUB-1.97. Split the
|
||||
build/install portion from the configuration of /boot and
|
||||
the mbr and placed the build portion in Chapter 6.
|
||||
Expanded the discussion about the /boot mbr portion in Chapter 8.
|
||||
Fixes <ulink url="&lfs-ticket-root;2093">#2093</ulink>.
|

This also eliminates the need for an initramfs as

specified in

<para>GRUB uses its own naming structure for drives and partitions in

the form of <emphasis>(hdn,m)</emphasis>, where <emphasis>n</emphasis>
|
||||
is the hard drive number and <emphasis>m</emphasis> is the partition
|
||||
number, both starting from zero. For example, partition <filename
|
||||
class="partition">hda1</filename> is <emphasis>(hd0,0)</emphasis> to
|
||||
GRUB and <filename class="partition">hdb3</filename> is
|

<emphasis>(hd1,2)</emphasis>. In contrast to Linux, GRUB does not
|
||||
number. The hard drive number starts from zero, but he partition number
|
||||
starts from one for normal partitions and five for extended partitions.
|
||||
Note that this is different form earlier versions where
|
||||
both numbers started from zero. For example, partition <filename
|
||||
class="partition">sda1</filename> is <emphasis>(hd0,1)</emphasis> to
|
||||
GRUB and <filename class="partition">sdb3</filename> is
|
||||
<emphasis>(hd1,3)</emphasis>. In contrast to Linux, GRUB does not
|
||||
consider CD-ROM drives to be hard drives. For example, if using a CD
|
||||
on <filename class="partition">hdb</filename> and a second hard drive
|
||||
on <filename class="partition">hdc</filename>, that second hard drive
|
||||

|

|

<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 100 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">hda4</filename>.</para>
|
||||
class="partition">sda2</filename>.</para>

<para>Tell GRUB where to search for its
|

<filename>stage{1,2}</filename> files. The Tab key can be used

everywhere to make GRUB show the alternatives:</para>

<para>Install the GRUB files into <filename

<screen><userinput>root (hd0,3)</userinput></screen>
|

<screen role="nodump"><userinput>grub-install --grub-setup=/bin/true /dev/sda</userinput></screen>
|
||||
|
||||
<para>We use --grub-setup=/bin/true for now to prevent update the
|
||||
Master Boot Record (MBR). In this way, we can test our installation
|
||||
before committing to a change that is hard to revert.</para>
