Hi,
When doing guix system system.scm /path/to/empty/directory, I have the
following error message:
> # guix system --verbosity=99 --debug=99 --no-bootloader init
> system.scm /srv/distros/guix/ guile: warning: failed to install locale

so I'm probably doing something wrong here as I'm probably not supposed
to abuse guix system init to create chroots for lxc.
However the issue is that there is no clear error message nor backtrace
telling me what exactly is wrong here. I don't even have a line in my
file that tells me what line is wrong.
I've attached the system.scm used for reference.
Denis.

It seems you've addressed the problem thoroughly, thank you!
