> guix system disk-image --file-system-type=iso9660 \
>   gnu/system/install.scm
> 3. boot it
> 4. switch to tty3

> 6. guix build -f gexp.scm

> This will fail with as strange error message.
> This same problem causes the final installation failure in the installer.

> This works fine on the latest installation image.
> This works if you run it again after it fails.
