Hello,

I'm updating my guix repository in Debian/Hurd with the commit 40f5c53d89da266055a1dd6571c380f5c57fe5f9.
When I run `sudo ./pre-inst-env guix system init doc/os-config-hurd.scm /guix --fallback --no-substitutes --no-build-hook` show the error:

`

I have reviewed the code in (scripts system), but I have not had luck; Any idea what's happening?

Attachment operating system configuration template.

Thank you
Rene
