No, you should use the files in kernelsource.dsl (not really the full source)
OK, I can see there is a .config file in the kernelsource dsl file. Whay is ist so different to the dsl.config that is filed with the kernel for 2.4.31 in the download ftp area? All I want to be able to do is recompile the 2.4.26 kernel exactly as it is for v3.4.11. I appreciate these are for different kernels, but I am surprised ath the different in size of the files (i.e. the number of changes made in .31 from .26.).As the config options change, then the config file changes too..
