Hi,

Trying to install guix-0.15 to see if I can get dual booting with btrfs
working on my laptop. But didn't get that far. Encounter an error when
running guix system init. Ran it twice, same error. Any idea what could be
wrong? Took about 4-6h to run it the first time.

Here's the command:
guix system init /mnt/etc/config.scm /mnt/ --substitute-urls="
https://hydra.gnu.org https://berlin.guixsd.org"
And here's the output of the second run, minus a bunch of substitute:
updating...

I attached my config files, 00-keyboard.conf is placed in /etc/config.d

Thanks
