Kernel modules

How would I go about adding kernel modules permanently to my GuixSD system?

Currently I think I need to:

1. write a package definition that install the module to the store
2. install that package
3. tell GuixSd somehow to load the module on boot

How do I do 3. ?

Also if there's a good example in the source code, please point to it. (I
looked at the nouveau video driver, but it is just using a plain gnu build
system and that's it)

This is discussed in the following section of the manual:

  (guix) Initial RAM Disk

For example, you can specify extra kernel modules to load in the initrd
via the #:extra-modules keyword argument to the 'base-initrd'
procedure.

Hope that helps get you started!

Note that this section of the manual is about loading modules from the
initrd.

My understanding is that Johannes would instead like to have out-of-tree
modules (modules not part of linux-libre) loadable once the system is
booted.  Is that correct?

In that case you’d need to arrange to have these modules in
$LINUX_MODULE_DIRECTORY.  There’s currently no easy way to do that, but
this could be added.

HTH!
