[sarcasm]And all this time, decade+, I though the ability to recompile especially the kernel was the main difference/advantage between a source based O.S. and a binary-only O.S. I don't know how you came out with the statistics but I have a funny feeling you are 100% wrong.[/sarcasm] Everybody should want to recompile the kernel, if not for the experience, but for removing the bloat. Does everybody really need every chipset compiled in the kernel! If the degree of dificulty of building a custom kernel on Centos change from the traditional method (make clean, make mrproper, make xconfig, etc) than say so, and point to an authoritative howto guide, if there is any. But whatever you do please don't insult by deciding for 98% of us what is and what is not "something you really want to do". I can only speak for myself, and I really want to be able to recompile the Centos kernel, otherwise I wouldn't waste my energy asking a zillion times how to compile Centos' kernel. Second irony (from second hand information) is that the vanila kernel compile just fine on Centos using the traditional method. --- Maciej ¯enczykowski maze@cela.pl wrote: > That's because 98% of the time recompiling the > kernel is not something you > really want to do, and the remaining 2% of the time > you just use > rpmbuild --rebuild kernel-.....src.rpm > > And if that doesn't work _then_ you're out of luck > (the above works for me > with a couple different kernels).
