Hi Danny,

I have simply tried:

   docker run -d --name guix registry.gitlab.com/daym/guix-on-docker
   docker exec guix guix pack hello

Wow!  The image is huge:

5.23GB registry.gitlab.com/daym/guix-on-docker latest 884b4a4ddf61 

Is it expected?   BTW, I am noting that there are couple of layers:

I am not sure to understand why.  It reminds me this previous thread:

<https://yhetil.org/guix-user/CAKjnHz1X26QhPEWZfOmAbEmZHQA1qdU_Dq7U6kVXUqG7vCvuhw@mail.gmail.com>

Well, I do not know.


Then, the ’docker exec’ downloads \o/ and then fails with:

  guix pack: error: getting status of `/tmp': No such file or directory

Hum, as in the other message, I am sure I am missing the obvious with
Docker options.

Currently, it builds master, right?  I have not looked but do you think
it could possible to track the both branches master and version-1.x.y?
