I think what we need is pflask:

A container is programs or full os running in an isolated environment.
For a full container with rootfs, we can:
  build the rootfs:
    of Guix:    by using a form of `guix system init'
    of Debian:  by using debootstrap

  get it running:
    # pflask --chroot=rootfs /sbin/init
For a lightweight container without rootfs, we can:
  build the activate script by `guix build'
  get it running:
    $ pflask --user=$USER activate
    (could run by normal user by using User namespace)

Isolation is archieved by using Linux namespaces, IMO dmd will work
