WARNING/NOTE: whenever you want to add an option here you need to
|
|
either
|
|
|
|
* mark it as an optional one with `?` suffix,
|
|
* or make sure it works for all the versions in nixpkgs,
|
|
* or check for which kernel versions it will work (using kernel
|
|
changelog, google or whatever) and mark it with `versionOlder` or
|
|
`versionAtLeast`.
|
|
|
|
Then do test your change by building all the kernels (or at least
|
|
their configs) in Nixpkgs or else you will guarantee lots and lots
|
|
of pain to users trying to switch to an older kernel because of some
|
|
hardware problems with a new one.
