There is a caveat with `guix copy`: if you copy the grafted derivation
(as the `guix system build` closure would be) the receiving system won't
recognize it since it only computes the ungrafted derivations.

If you build the system with --no-grafts, I suspect things will work as
expected.

Probably :)
