The purpose here is to avoid the "pivot-root" call that is done
unconditionally in "mount-file-systems". This way containerized process
can share the parent root file-system.

Maybe something like that would make more sense:

--8<---------------cut here---------------start------------->8---
(lambda ()
    (unless (null? mounts)
      (mount-file-systems root mounts
                          #:mount-/proc? (memq 'pid namespaces)
                          #:mount-/sys?  (memq 'net
                                               namespaces))))
--8<---------------cut here---------------end--------------->8---

Thanks,

Mathieu
