guix system docker-image: nix not found

Hi all,

I've been playing around with docker containers and guix (both to 
package software, and to eventually fit "building guix packages" into a 
docker-based CI pipeline).

The guix manual mentions that apart from `guix pack`, `guix system` can 
also build docker images of whole system configs, which seemed fitting, 
but it lacks an example, and I'm a bit unclear on some points. In 
particular, I don't know what to set for the bootloader and file-systems 
options in the system config, as neither really applies to a docker 
container (I tried not setting them at all, but guix doesn't allow that).

When trying with dummy values (taken from my own system config),
`guix system docker-image system.scm` fails to build the
guix-docker-image.tar.gz.drv, and the build log contains

   /gnu/store/...bash-5.0.16/bin/bash: nix: command not found

which doesn't really help.

I'm on a current guix system, i.e. `guix describe` gives:

   guix 069399e
     repository URL: https://git.savannah.gnu.org/git/guix.git
     branch: master
     commit: 069399ee9dbf75b7c89583f03346a63b2cfe4ac6

Thanks!

It would help if you sent the entire log file as an attachment.

nevermind; I thought that /was/ the entire logfile, but it turns out 
that I had the emacs nix-mode installed, which recognised the logfile as 
a derivation and tried to call nix to parse it, and apparently its 
failure mode (since I don't have nix installed) was to write its own 
stderr into the buffer without giving any indication that wasn't the 
real content of the file …

The actual logfile is of the vm running out of memory, which is a known 
issue [1]; I'll look into how to solve that.

Sorry for the unnecessary message, but thanks anyways for responding :)

Oh... we need to fix that. Sorry for the roadblock.
