[Nix-dev] How to replace a standard kernel module with a newer version?

[Peter Simons]

Hi guys,

the standard Linux kernel has a module e1000e. Unfortunately, that
module is too old for my network card, so I need to use the new version
which is packaged in "linuxPackages.e1000e". Now, I assumed that setting

  boot.extraModulePackages = [ config.boot.kernelPackages.e1000e ];

in configuration.nix would do the trick, but of course the build
complains about a file collision:

  collision between
  `/nix/store/0ia6qcpww8sja79hc9rfcxq4cim356bb-e1000e-1.5.1/lib/modules/2.6.38.8/kernel/drivers/net/e1000e/e1000e.ko'
  and
  `/nix/store/s9mhjmacl0grg9qndyr0xy1lfc46ww3f-linux-2.6.38.8/lib/modules/2.6.38.8/kernel/drivers/net/e1000e/e1000e.ko'
  at /nix/store/1pwj1c26h0vi5w535iw2ipd26zd6k6hq-builder.pl line 72.

Does anyone have an idea how I might remedy that issue?

Take care,
Peter
