streamline_config.pl is a very powerful tool. For those that install a kernel to a new box using the config file from the distribution know that it can take forever to compile the kernel. Making a custom config file that will still boot your box, but bring down the compile time of the kernel can be quit painful, and to ask someone that reported a bug to do this can be a large burdon since that person may not even know how to build a kernel. This script will perform "lsmod" to find all the modules loaded on the current running system. It will read all the Makefiles to map which CONFIG enables a module. It will read the Kconfig files to find the dependencies and selects that may be needed to support a CONFIG. Finally, it reads the .config file and removes any module "=m" that is not needed to enable the currently loaded modules. The output goes to standard out. Here's a way to run the script. From the Linux directory that holds a distribution .config. $ scripts/kconfig/streamline_config.pl arch/x86/Kconfig > config-sl $ mv .config config-save $ mv config-sl .config $ make oldconfig Now you have a .config that will still build all your modules, but also take much less time to build the kernel.
