I’m writing an article series about : “Remastering openSUSE : How to Build your own openSUSE Based Distro” as part of my presentation at Indonesian openSUSE Community monthly meeting  last week. The article based on my experience while making openSUSE 11.0 KDE 3.5+Multimedia Support LiveDVD (beware with it’s restricted media if you want to rebuild this. I make it as part of my presentation tutorial).
I’ve posted 2 article for now, “Kiwi as imaging system and how to install it on openSUSE” and “How to build openSUSE Minimal System LiveCD”  and currently writing the third article “How to make openSUSE 11.0 KDE 3.5 LiveCD”

It was not a completed tutorial but I hope it could helped you for making openSUSE with your own specification. Sorry for any inconvenience.
Note : The term “Remastering” would not correct either, because I simply described how to make openSUSE with our specified configuration and application without change any openSUSE branding, splash screen or another openSUSE trademark.
