I was just curious whether i can remove the .config file. Actually i am learning how to edit the config (from make menuconfig) and recompile the kernel. So if i remove the .config file from the source (/usr/src/linux) how does it affect? I am learning from this link


If you delete the .config file then you'll have to start the kernel configuration from total scratch (selecting the architecture and so on). There is also the possibility to start with a "default configuration" by using the

make XXXX_defconfig

Where XXXX is the system you are working on (for example i386). This default configurations are found in arch/XXX/configs directories (with XXX being the architecture).

Also some environment/Makefile settings are used from the kernel to assist you in this process (for example the ARCH variable is used to filter out the architectures proposed)
