Right. Currently the installer is rough on the edges as you’ve seen,
but it would be good to a least give pointers to ‘loadkeys’ and similar
commands.
Would you like to propose a patch? The manual lives in doc/guix.texi in
the repository.

I’m afraid I don’t fully understand what’s supposed to happen and what
doesn’t work here.

Great. This issue is being discussed at <http://bugs.gnu.org/20433> and
we were waiting for confirmation of exactly which modules need to be
added to the initrd.
The initrd already contains ‘usbhid’ by default. From what I can see,
all that’s missing is ‘hid-generic’ and ‘hid-apple’:

Is there a risk of conflict if we load all these drivers? If not, let’s
just add them.

OK. Someone™ should package it, then.

No idea about that one. Could it be that our Xorg is not loading the
right input driver(s)? Could you compare /var/log/Xorg.0.log with what
you get on a “working” distro?

Thanks for sharing your problems and solution—that’s how we
incrementally manage to improve things.
So you have a fully-encrypted system, with an unencrypted /boot, right?
Does the grub.cfg generated by ‘guix system’ work for you? Did you have
to run the ‘insmod’ and ‘cryptomount’ commands in GRUB as reported at
<http://bugs.gnu.org/21843>?
Thanks,
Ludo’.
