/*

|
|
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.

nixos: make several kernel common-config options optional
Realistically, common-config is useful, but there are a lot of things in
there that are non-optionally specified that aren't always useful. For
example, when deploying grsecurity, I don't want the bluetooth,
wireless, or input joystick/extra filesystem stack (XFS, etc), nor the
staging drivers tree.
The problem is that if you specify this in your own kernel config in the
grsecurity module, by saying 'BT n' to turn off bluetooth,
common-config turns on 'BT_HCIUART_BCSP y', which then becomes unused
and errors out.
This is really just an arbitrary picking at the moment, but it should be
OK.

nixos: make several kernel common-config options optional
Realistically, common-config is useful, but there are a lot of things in
there that are non-optionally specified that aren't always useful. For
example, when deploying grsecurity, I don't want the bluetooth,
wireless, or input joystick/extra filesystem stack (XFS, etc), nor the
staging drivers tree.
The problem is that if you specify this in your own kernel config in the
grsecurity module, by saying 'BT n' to turn off bluetooth,
common-config turns on 'BT_HCIUART_BCSP y', which then becomes unused
and errors out.
This is really just an arbitrary picking at the moment, but it should be
OK.

nixos: make several kernel common-config options optional
Realistically, common-config is useful, but there are a lot of things in
there that are non-optionally specified that aren't always useful. For
example, when deploying grsecurity, I don't want the bluetooth,
wireless, or input joystick/extra filesystem stack (XFS, etc), nor the
staging drivers tree.
The problem is that if you specify this in your own kernel config in the
grsecurity module, by saying 'BT n' to turn off bluetooth,
common-config turns on 'BT_HCIUART_BCSP y', which then becomes unused
and errors out.
This is really just an arbitrary picking at the moment, but it should be
OK.
