What difficulties did you encounter with using allmodconfig as a basis?

I agree that how nixos does it seems a little fragile. From what I've
heard the kernel settings and their defaults change frequently with
each release. This is why I think relying on the kernel devs to
provide reasonable defaults makes more sense IMO.

I'd like to make it easy to build custom kernels, I remember using an
auto detect config feature a while back when using arch. But before
working on that I need to actually transition to guixsd...
