How about a directory called /usr/share/Linux/Kconfig.d/

Then have anything installed that needs to work correctly put in its
minimum (must have) requirement configs of the kernel.

Say you are running Debian, and decide to try out systemd. If you set up
your system to run that it would add a file called:


or something, and this would select things like CGROUPS and the like. We
could make the kernel build select all, or individual files in this
directory. All for the 'make my distro work' or individual for a 'I want
part of my distro to work' option.

A reasonable one, but still not the minimum.

One issue with Linus's proposal is that he's asking us to focus on the
99%. But the 99% of who? Because 99% of Linux users do not compile their
own kernels, so he must be asking about the 99% of Linux users that
compile their own kernels. This 99% does not just simply compile their
kernels, but only want to compile the absolutely necessary stuff. That
is, they want their kernels not to include anything they are not using.

A reasonable config would probably need to include a lot that's not
