O.K.-this is what I mean:
When I do a compilation of the kernel I can save configuration to the file,right? And later on if I want to add the feature to that kernel all I have to do is to open make xconfig and load the configuration file and then add some featues.
I was wondering if there is such a config file for EXISTING kernel that I can load and add netfilter support instead of compiling the new kernel......
The logic is pretty simple-when I compile a new kernel I have to choose all the options myself, and no matter how long I dig help in make xconfig I still am not sure that I added all features needed for the new kernel, so the easiest thing would be for me to take the existing kernel and add some features (like netfilter) to it-I just don't know if it possible.
As to the fact that rh kernel doesn't have a netfilter support out of the box-I must agree 100% that this is absolutely weird.
