problems with offloading

[ng0]

Hi,

because last time I didn't document and didn't save the config I have to
ask again. I'm running into the issue where I can't offload but I
followed all instructions. This time it will go into my documentation.

Both systems are up to date (reconfigure and pull), both are running
GuixSD.

>From master to offloading machine the test (imagine foo.local being a
valid IP/domain):
address@hidden ~> guix offload test
guix offload: testing 1 build machines defined in '/etc/guix/machines.scm'...
guix offload: 'foo.local' is running guile (GNU Guile) 2.0.13
guix offload: error: failed to use Guix module on 'foo.local' (test returned 
#<unspecified>)

Okay, now let's log in to see if (guix config) is realy not a module in
the profile.

address@hidden ~$ guile

scheme@(guile-user)> (use-modules (guix config))
scheme@(guile-user)> (quit)



so far so good, no errors when loading it. So let's run this guile -c by
ssh command:

address@hidden ~> ssh foo.local guile -c "'(use-modules (guix config))'"
address@hidden's password:

The offload/build machine has: guile in its profile and has every other
requirement the offloading section of the documentation wanted.
I'm currently turning it into an local bayfront/hydra copy, but the
error existed before I started this.

So, what's wrong here? Any clues, any more info you need?
