Building arm64 guix system image

[Max Brieiev]

I want to run Guix on Apple M1 as a Qemu virtual machine.

On the Mac machine I run arm64 dedian image. I installed there guix as a
package manager. Now I am trying to create a guix system image to use
with Qemu, but it fails.

Here is what I do:

    max@debian:~$ guix system image --system=aarch64-linux -t qcow2 
~/code/guix/gnu/system/examples/bare-bones.tmpl 
    guix system: warning: Consider running 'guix pull' followed by
    'guix system reconfigure' to get up-to-date packages and security updates.

The relevant part of the build log shows the following errors:

I don't know where to look to fix this error. Please, help me.

Also, I thought I could find somewhere arm64 guix build, but apparently
there is none?

I found only a raw image for Pinebook Pro:
https://ci.guix.gnu.org/eval/196495

But for some reason it says it is x86_64 system, and this confuses me.

Thank you in advance.
