guix pack -f docker ...

[Yoshinori Arai]

Hello,

I'm trying possibility of guix pack especially docker or squashfs for
singularity.

I have tried guix pack -f docker emacs geiser guile.
$ cp /gnu/store/ywrxbn8ik9bmj4xhd5yybwvs069v9vv9-docker-pack.tar.gz \
  ./emacs-geiser-guix.docker.tar.gz
$ docker load < emacs-geiser-guix.docker.tar.gz
$ docker images

$ docker run -it --name my-emacs profile:zy3irqp7vsiyk28ns3xliakll07p9cz4 emacs
docker: Error response from daemon: OCI runtime create failed:
container_linux.go:344: starting container process caused "exec:
\"emacs\": executable file not found in $PATH": unknown.

I don't know about docker well.
This traial was on foreign distro debian 9. Docker was installed from debian.
Please tell me how to use guix pack -f docker ...

Thank you.
