This option allows you to override the Linux kernel used by
NixOS. Since things like external kernel module packages are
tied to the kernel you're using, it also overrides those.
This option is a function that takes Nixpkgs as an argument
(as a convenience), and returns an attribute set containing at
the very least an attribute <varname>kernel</varname>.
Additional attributes may be needed depending on your
configuration. For instance, if you use the NVIDIA X driver,
then it also needs to contain an attribute
