>Description:
I would like to propose changes to the GENERIC kernel configuration, which
would IMHO produce a more uniform, universal, and easier to manage default
system kernel.
Two simultaneous routes are to be taken:
1. Taking full advantage of the kernel's already present modular design by not
compiling anything that exists as a module into the kernel. Let the boot loader
load all those modules that are presently compiled into GENERIC, and allow
the kernel to stay small and lean.
2. Compiling all available "reasonable" non-modular drivers and features into
the kernel and its supporting modules.
>How-To-Repeat:
Nothing to repeat.
>Fix:
This is a sample configuration which could serve as an overview of the general
idea. It is the actual configuration that I use to build a universal "GENERIC
substitute" kernel for all my machines.
