Your contributions in this area would be welcome!


Ideally I would like it to be mounted on boot. Only thing I found was in
the mount manpage <https://linux.die.net/man/8/mount> which mention the
option _netdev. That will supposedly wait until the network is up before
mounting. But I'm not sure if GuixSD (Shepherd?) is using mount or not.

How do I mount it manually after boot? I see it's in the fstab but I cannot
run mount. It's complain about wrong fs type, bad option, bad superblock...
And mention that it might need a /sbin/mount.<type> helper program. When I
run
sudo mount /media/Valhalla

I would love to contribute. But my experience with guile right now is
minimal. So my plan is to first familiarize myself with guile and guix by
first package up some stuff I notice are missing in guix that I use. Any
recommendations on books, tutorials etc on guile would be helpful.

This worked for me. Thanks. What is the best way of looking up what package
belongs to what module? In case I hit more of this in the future.

Tried doing something similar but getting errors on the read-string.
First I got:
guix system: error: failed to load '/etc/config.scm':
/etc/config.scm:23:24: /etc/config.scm:23:24: In procedure module-lookup:
Unbound variable: read-string

After searching in the guile manual I found a read-string in the module
(sxml ssax input-parse), loaded that and now I get.
guix system: error: failed to load '/etc/config.scm':
sxml/upstream/input-parse.scm:318:11: In procedure read-string:
sxml/upstream/input-parse.scm:318:11: In procedure <: Wrong type: #<input:
/etc/config.d/00-keyboard.conf 14>

I'm probably missing something.
I've attached my new config.scm and xorg file.

Not sure about this one.  Your config looks okay to me.  I’m not using

It is working it was just me being stupid. I was looking in /bin for env,
but in my config it is set to /usr/bin/.

I'm not sure about this one either. No kernel firmware mechanism is
involved as far as I know, I think the firmware just mimics a plain old usb
keyboard. From what I understand the dual action keys should be happening
in the firmware and the kernel shouldn't even notice any of this. But
that's just my assumption. Need to debug this further before I can draw any
conclusion if it's GuixSD or if it's my laptop. Just thought I mention it
in case someone have stumbled across it.
