Is there any step-by-step docs/samples on how to create a patch ?
Did you look at http://www.turnkeylinux.org/docs/tklpatch?
Thankyou for your response
Yes I read that docs, but it still confusing me ...
Ok I'll re-read it better
I was not trying to be mean. I have not yet tried to use tklpatch and did not know if you found the instructions page. I wish I could be more helpful, but I am new to TKL and trying to learn too!
Often with these sorts of thing it can be difficult to get your bearings at first. The key is to experiment. Try making a tiny proof of concept change and work up towards larger changes.
Also, remember that there is a reference example patch for you to examine and play with in /usr/share/tklpatch/examples.
