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
|
|
|
|
|
<varname>nvidia_x11</varname>.
