I would like to how how I can take the CentOS 4.4 Server Cd for example and modify the ISO to put on my anaconda-ks.cfg file and then modify the kernel parameters to automatically load the anaconda-ks.cfg file so that I can create a CD that I just stick into my machine it will format the drive, install the basic configuration I like without asking any questions. I need to install like 20 machines and I wanted to basically just stick a CD in the drive and let it do it's thing.
Any help on how to accomplish this would be appreciated.
Here's how I did it for RHEL CD's
--------------------------------------------------
Construct a single DVD from the four RHEL CDRom's
Insert & mount CD1
# mkdir /DVD # mount /dev/cdrom /media/cdrecorder
Copy cd1 to /DVD
# cd /media/cdrecorder # tar cf - . | (cd /DVD ; tar xvf - .) # cd / # eject cdrom
Carry out the above action for CD 2-4
After all CD's have been copied.
Correct the .discinfo file to reference all four disks.
# cd /DVD # vi .discinfo
Ensure line 4 has 1,2,3,4 A working .discinfo should be as follows.
# cat .discinfo 1141417589.425945 Red Hat Enterprise Linux 4 i386 1,2,3,4 RedHat/base RedHat/RPMS RedHat/pixmaps
Create the bootable ISO file. (all on one line)
# mkisofs -A "RHEL/4.3 i386 3AS" -o DVD.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T /DVD
Burn the DVD.iso as an image not a file.

Modify the DVD to include custom kickstart scripts.
Create the /DVD tree as per the previous steps.
The default files read on boot up of an RH install CDRom are located in /isolinux/
To run custom kickstart scripts we need to modify the /isolinux/isolinux.cfg and add the kickstart file to the boot process. See here for kickstart script generation.
For each kickstart install we need to add 3 lines to the isolinux.cfg file.
A label line - This is the identifier you type at the linux boot prompt A kernel line - This does not change A append line - This is where we tell the boot process to use a kickstart file.
Firstly backup the original file.
# cp /DVD/isolinux/isolinux.cfg /DVD/isolinux/isolinux.cfg.orig
Now edit and add our custom kickstart file.
# vi /DVD/isolinux/isolinux.cfg
Add
label myboot1 kernel vmlinuz append initrd=initrd.img ramdisk_size=8192 ks=cdrom:/ks.cfg
This will enable you to type myboot1 at the boot prompt which will call the ks.cfg located in the / of the DVD disk.
Multiple kickstart files can be added by using different label and append lines.
For Example:
label myboot1 kernel vmlinuz append initrd=initrd.img ramdisk_size=8192 ks=cdrom:/ks1.cfg label myboot2 kernel vmlinuz append initrd=initrd.img ramdisk_size=8192 ks=cdrom:/ks2.cfg

Have fun.
