About this tutorial. This is what we call the root directory; it is the underlying directory for all files. A vast part of the source code of the kernel is stored in the device drivers, and that makes a specific hardware device usable. Kernel Module Configuration with make Rules. The general understanding is that the files are a sort of in a tree structure on the main hard drive; this is for easy management and order.
