What you see here most likely means that host2 threw an exception while
executing this code:

  http://git.savannah.gnu.org/cgit/guix.git/tree/guix/scripts/offload.scm#n=
543

The reason could be:

  1. That the (guix =E2=80=A6) modules could not be found in the search path
     (your tests suggest this is not the case);

  2. That an exception was thrown, for instance because the =E2=80=98with-s=
tore=E2=80=99
     form failed to connect to the daemon on that machine (is the daemon
     running on that machine? Is it listening on
     /var/guix/daemon-socket/socket and not some other place?).

We should definitely improve that and provide details about the
exception, at least.

HTH!

Ludo=E2=80=99.
