Yes.

Yes.

Guix install, shell or pull.  And yes, some are stopped but some (for
instance elasticsearch) still run.

As follows:

  $ docker ps
  CONTAINER ID  IMAGE           COMMAND                  CREATED         STATUS        PORTS     NAMES
  $ docker run -d postgres:10.10
  ..
  2b52ee072b1f5584cae597afb033cdcc0e560bbe9145b17b41502c204034e60b
  $ docker ps
  CONTAINER ID  IMAGE           COMMAND                  CREATED         STATUS        PORTS     NAMES
  2b52ee072b1f  postgres:10.10  "docker-entrypoint.s…"  2 seconds ago   Up 1 seconds  5432/tcp  blah_blah
  $ guix shell xeyes -- xeyes

  $ docker ps
  CONTAINER ID  IMAGE           COMMAND                  CREATED         STATUS        PORTS     NAMES
  $ exit

First we see no docker containers are running, then we start postgres-10
from docker hub, now we see its container is running, then we do
something using guix-shell on an application *not already available on
this system*, now the container died.  This does not work the second
time when the "derivation" is already "built".

Weird huh?
