Yeah. It's after doing

	git clean -dqfx
	make oldconfig

where I tend to use "git clean -dqfx" instead of "make mrproper" these days.

Note that my "oldconfig" really only does the things I need, so this is _not_ a "allmodconfig" or anything like that. That would take much longer. It only has the drivers I use, and the stuff I actually need (it's not a embedded kernel in any way, but it's definitely pared down config exactly because I like being able to rebuild my kernels without wasting time on thousands of drivers that I can't use anyway).

Other people can do the "does it compile?" testing. Not worth my time, I feel ;)

Well, the difference really is the beefy box. And the fact that I hate modules, and I hate building stuff that I don't actually need.

I literally turn off CONFIG_MODULES entirely.
