Hello Jan,

I strongly suspect this is because we would need to wrap the
"compile-file" call in "scm->go" procedure of (gnu services shepherd)
inside a "with-target".

That would look like:

--8<---------------cut here---------------start------------->8---
(if target
    (with-target target
                 (compile-file #$file #:output-file #$output
                               #:env env))
  (compile-file #$file #:output-file #$output
                #:env env))
--8<---------------cut here---------------end--------------->8---


Now, the tricky part is the value of target, because
#$(%current-target-system) might not be correct in that context.

Mathieu
