CD creation

İçindekiler

This should be a HowTo to create an adapted openSUSE CD. So you can easily produce a special "product CD" for example:

So the main targets to describe here should be:

thinking about the packages you need, create a beautiful CD Layout (documentation, splash screens, specialised windowmanager if wanted, ...)
describe the needed tools and scripts to create the iso image
after that: thinking about "maintainance": if you have specialised packages on you CD you'll probably want to update these packages with YOU or another tool

For boot-images: Some beautiful images can be created with different tools like gimp. The imaging tools should be able to create *.png and *.jpg. You can create different sizes with "convert" - so the best way should be to create the biggest sized image and convert them to lower sizes.
a RPM-Repository (this could be a DVD, a local filesystem, FTP, ...) with the needed RPMs

At first take a look at the current CD Layout of an openSUSE-CD.

CD layout table
boot	contains files for booting from CD (rescue image)
ARCHIVES.gz	contains a list of all files and the RPMs containing these files
ChangeLog	Changelog of all RPMs since the last release
INDEX.gz	a list of
+	loader	contains different kernel and vmlinuz images, language files an bootsplashes
content	information about the CD. Important: YaST2 searches for his YOUPATH in this file.
control.xml	this file controls the installation workflow.
docu	contains documentation for "online reading"
gpg-pubkey-*	different gpg-keys - all of them will be included in the root rpm-keyring so rpm trusts every rpm that is signed with these keys
ls-lR.gz	what the filename says: the output of "ls -lR" for the whole CD
media.1	directory containing different informations (like license and CD-version) about the current CD
suse	directory with RPMs and setup data
+	setup
+	-----	descr	contains (many) package selections (known from YaST2-Packagemanager) EXTRA_PROV - during installation YaST2 must know something more than RPM about depencies; this file contains all extra "provides" for packages packages.<language> files containing language specific descriptions for all RPMs selections - a file containing all available selection files
+	-----	slide	contains pictures and texts showing during installation (dia-show)
