cd ..
# get the file list in the new image
gunzip -dc initrd-${kern}.img | cpio --quiet -it | grep
-v '^\.$' | sort -o New-listing
# and show the differences.
echo -e '\nChanges in files in initrd image\n'
diff Orig-listing New-listing
# copy the new initrd to wherever you have configure the
dhcp server to look
# for it (here we assume it's /images)
mkdir -p /images
cp initrd-${kern}.img /images
echo -e '\nCompleted initrd for IB'
ls -l /images/initrd-${kern}.img
c. Run the
usr/share/infinipath/gPXE/gpxe-qib-modify-initrd
script to create the initrd.img file.
At this stage, the initrd.img file is ready and located at the location
where the DHCP server was configured to look for it.
5. Create auniboot.php file and save it to /vault/images/uniboot.
NOTE:
The uniboot.php generates a gPXE script that will attempt to
boot from the /boot/vmlinuz-2.6.18-128.el5 kernel. If
you want to boot from a different kernel, edit uniboot.php with
the appropriate kernel string in the $kver variable.
