Building Installation Disks

To build a new installation disk:

Mount the skeleton ISO:

Now, copy all the files on it to an ordinary directory on your system:

The mounted ISO is no longer needed, so can be unmounted. Inside the copied files, the following are available:

Item	Description
data	Contains a file called data.tgz which contains the bootstrap program.
isolinux	The CD boot files. Don't touch these unless you know what you're doing!
lost+found	Not used

The data.tgz file is a compressed tar file that contains the bootstrap program. This program can be anything, from a simple shell script to a complex application.

The running system is in a RAM disk (which has limited size). The boot.tgz file is extracted into /opt/boot. Once the extract is complete, the installation disk attempts to run an executable at /opt/boot/bootstrap. Thus, create a tar file called data.tgz with a bootstrap program in the "root" of it. There is a template in the CDROM image.

To make a new CDROM image, change directory to the root of the CD image, and run:

Then, burn the image to a disk and you're ready to go!
