Yeah, grepping and modifying kernel configurations in that way is
always a bad idea IMHO.
For instance, It's incorrect to set CONFIG_X86_PAE=n like because in
this case the kernel has pae built in which cannot be disabled if
highmem= 64GB.
Highmen needs to equal off or 4GB to disable pae.

I just found this out, So it's worth mentioning.

I really, Really need to use menuconfig (ncurses) In NixOS to build
kernel configurations.
Is there a way to setup paths so that I can do so?
Do I just call make straight from it's location in the store because
it's not in a regular user's path?
Or install make and possibly ncurses into a user's environment? It's
already installed system wide.

Thanks,

Tony
