132 Running Deployment Scripts and RPMs Using DTK and Embedded Linux
5 In /mnt/cdrom/isolinux.cfg , edit the cd install section to point to your
customized start-up script. In other words, add the
share_script
option; for example:
label 1
kernel SA.1
append initrd=SA.2 ramdisk_size=55321
Stage3_type=cdrom DEBUG=0 quiet share_type=cdrom
share_script=dracupdate.sh
Then, use mkisofs to make your customized media image; for example:
mkisofs -o usaf.iso -b isolinux/isolinux.bin -c
isolinux/boot.cat -no-emul-boot -boot-load-size 4
-iso-level 2 -relaxed-filenames -r -J -pad -boot-
info-table /root/usaf/
NOTE: It is important to use mkisofs to make your customized image
because the ISO Linux recognizes only the isolinux.cfg (and all files within
/isolinux). If you do not use
mkisofs, HAPI libraries of DTK cannot load and
most of the Dell Update Packages cannot work.
NOTE: The scripts that you copy into the media are copied to the RAM disk
and run from the RAM disk. This task is done to ensure the media is not
locked. Ensure that your sample scripts have valid path names.
6 Copy the directory structure created on your system into the root folder
that you created in step 3. This folder contains DTK media, files necessary
for operating system installation, and files required for replication.
7 Burn the contents of the folder you created in step 3 to a media. (Use the
isolinux utility to make the media bootable.)
8 Your ISO image is ready for booting.
