Thanks for the reply. That pointed me in the right direction. Although
the solution you suggested wasn't an option for me. As it turned out, it
was actually mounting my Arch Linux root (__current/arch-root). Which I
had set to be the default subvolume if no ~subvol=~ option is given when
mounting the disk.
Since my goal is to be able to dual boot, I don't want to nuke my arch
subvolume.
But that gave me an idea. What if I just change the default subvolume to
my GuixSD root (__current/guixsd-root). I did that and what do you know
it booted!
The question is though why did it mount my default subvolume? I
specified it to mount __current/guixsd-root for the root filesystem. As
well as setting that to be the subvolume to mount in the rootflags for
the kernel command line when booting. Is there a third step that I'm
missing?
In either case thank you so much for your help. Been trying to get this
going for over a year now. So it feels good to finally see the login
screen!
I attached my install log, which has all the steps I needed to do in
order to install GuixSD on a btrfs disk. In case someone is interested.

* Install guix-0.15
** Setup network and ssh locally
These things need to be first run locally on the machine you're
installing GuixSD.
**** Setup wireless and get ip
#+BEGIN_SRC sh
wpa_supplicant -i INTERFACE -B -c <(wpa_passphrase SSID PASSPHRASE)
dhclient -v interface
#+END_SRC
**** Setup ssh
Change the password to be able to connect to ssh
#+BEGIN_SRC sh
passwd
#+END_SRC
Then start the ssh service using shepherd
#+BEGIN_SRC sh
herd start ssh-daemon
#+END_SRC
** Install Process
NOTE: Change ~192.168.4.112~ to the ip you got from calling
~dhclient~ earlier.
**** Fix known_hosts
Note: If this is the first time, you can skip this step.
Remove guix from known_hosts, as its key changes every reboot.
#+BEGIN_SRC bash :dir ~/
sed -iE 's/^192.168.4.112 .*//' .ssh/known_hosts
#+END_SRC
**** Mount disks
This assumes that you have already setup an encrypted disk and
setup the following layout for ~/dev/sda3~.

Note that <hash> just indicates that there's a hash there, not that
all the hashes are the same. And that only update the path for the
bxImage and initrd and not the one for --system= and --load.
I.e add the modules to be able to decrypt (not sure if all are
needed) then set the correct path for the stuff in the
store. Keeping the hashes the same. I.e. you cannot just backup
grub.cfg then copy it back, as then you would just get the old
install.
After edit make it read only again, and you're done.

#+RESULTS:
**** Hack btrfs
Something doesn't seem to respect the mount options (rootflags)
when booting linux. Instead of mounting ~__current/guixsd-root~
as /, ~__current/arch-root~ gets mounted instead (Which is the
default subvolume.). That throws a wrench in the whole boot
process as GuixSD cannot setup the environment. You will see
errors like, "cannot symlink /etc/ssl, file already exist"
To work around that we need to change the default subvolume to
~__current/guixsd-root~.
Fetch the Subvolume id for ~__current/guixsd-root~, assumes it's
mounted at ~/mnt~.
#+NAME: btrfs-subvolume-id
