I am talking about using Linux's ability to build objects into a different directory than where sources are. This is achieved by using make O=. The idea is that it would avoid using rsync to copy the kernel sources when using a custom build directory because this takes both unnecessary time and space to do the initial copy into build/linux-custom.
