Before performing the procedures given below, make sure you have created backup copies of any
files you plan to change, specifically the
/srv/tftp/boot/initrd
file. If you want to change the
files on an imaging CD, you need an ISO editor or some other process for extracting and replacing
the file in the
bootcd.iso
image file.
IMPORTANT: When updating or adding files and Linux drivers in the
initrd
or
root
file
systems, document the changes you make. When you receive updated resource files from Novell,
they do not contain your customized changes. If the kernel version has changed with the newer
resource files from Novell, previously added drivers must be updated either by obtaining a new
version from the manufacturer or recompiling the driver using the correct Linux kernel version
source.

Š “Adding to Root” on page 653
To add files to the
root
file system, you can also use the
driverupdate
file method described in
Section F.4.3, “Using the Driverupdate File Method,” on page 654 .
Adding to Initrd
To modify the
initrd
file system:
1 Using a Linux device, create a working directory and change to that directory.
2 To copy initrd from the PXE server or the boot CD to the new working directory:
Š
For PXE, copy
/tftp/boot/initrd
to the Linux workstation’s working directory.
Š
For the CD, extract
initrd
from the
/boot/i386/loader
directory on the boot CD, then
copy the extracted
initrd
to the Linux workstation’s working directory.
3 To rename
initrd
to
initrd.gz
, enter:
mv initrd initrd.gz
4 To unzip the
initrd.gz
file, enter:
gunzip initrd.gz
5
To create another working directory for use as a mount point in the subsequent steps, enter:
mkdir work
cd work
6
To extract
initrd
into the
/work
directory, enter:
cpio -idmuv ../initrd >/dev/null 2>&1
7 To copy your files or updated driver to the extracted
initrd
file system, enter:
cp / your_path / module .ko work/lib/modules/2.6.5-override-default/initrd
where
your_path
is the path to the
module .ko
file and module is the name of the module.
Other files to be included in the
initrd
file system should be copied to the appropriate
directory.
8 To re-package the
initrd
file system, enter:
cd work
find . | cpio -quiet -o -H newc > ../initrd
cd ..
