Hi,
I've just finished a new article describing creating how to create a
modified installation system (for network-based installations).
You can find it here
http://en.opensuse.org/Linuxrc/Creating_Modified_Installation_System
Is is true that we already have a similar article at
http://en.opensuse.org/Creating_customized_installation_source
but the behavior has been changed a lot since openSUSE 11.0 Alpha2.
I've decided not to modify the old article because it is still valid for
openSUSE 10.3 and before, but I've linked them each other.
Have a nice day
Lukas
