kernel building instructions

This question is addressed at those with kernel building experience. The Fedora wiki has instructions on building a custom kernel: http://fedoraproject.org/wiki/Docs/CustomKernel That's good, thanks. Let's say that someone would like to build a kernel with different configuration options. He or she has created a new .config file. The relevant instructions are under the heading "Configure Kernel Options". Instruction 6 says the following: ===== "Copy the config file to ~/rpmbuild/SOURCES/: cp .config ~/rpmbuild/SOURCES/config-$arch" ===== The line above appears incorrect. This was recognized by another wiki editor as can be seen in the following sentences: ===== "In actual fact, a Fedora 11 x86_64 machine would use the following command, because the spec file has no config-x86_64 item, and so will not process it. The only spec entry is for generic. cp .config ~/rpmbuild/SOURCES/config-$arch-generic" ===== My question is this: what should be the name of the configuration file for Intel 32 bits architecture? config-x86 or config-i386 or config-i686 or one of the above followed by "-generic"?
