The Hurd has had this thing called “sub-Hurd”, which is similar to what
we’re talking about.

‘guix system container’ creates an executable that starts the container.
That executable is a Guile program that uses (gnu build
linux-container), a module that provides facilities to create processes
under separate name spaces, etc.

IOW all the functionality is provided by Guix; no systemd-nspawn,
bubblewrap, lxc, etc.
