New linuxPackages_custom helper function

[ts468]

Add linuxPackages_custom helper function for installing a Linux kernel with a custom config file.

[ts468]

As an example, I use linuxPackages_custom in my /etc/nixos/configuration.nix as in the example below. Is there another configuration option that achieves the same and is already included in NixOS?

boot.kernelPackages = pkgs.linuxPackages_custom {
version = "3.18.1-xen";
src = pkgs.fetchurl {
url = "mirror://kernel/linux/kernel/v3.x/linux-3.18.1.tar.xz";
sha256 = "13m0s2m0zg304w86yvcmxgbjl41c4kc420044avi8rnr1xwcscsq";
};
configfile = /etc/nixos/customKernel.config;
};

@jagajaga, glad you like it ;), could you maybe merge it?

[jagajaga]

Can you show /etc/nixos/customKernel.config?

[ts468]

It is just a standard kernel config file; what is it that you're looking for?

[jagajaga]

Hm. The problem is that I think that we have to document it somewhere.
May be for now you can just write some information in comments above your new code?

[jagajaga]

Some updates? :)

[ts468]

I think it would be best to put some note into https://nixos.org/wiki/How_to_tweak_Linux_kernel_config_options

[jagajaga]

Can you do it? Then I'll merge.

@jagajaga: So, I've updated the wiki. Could you please merge the PR?

[jagajaga]

Nice! Thank you.
