'guix' must be available on GUILE_LOAD_PATH on the remote machine,
e.g. by installing the 'guile3.0-guix' package into the user profile.

IOW, for offloading to work, this command should succeed:

$ ssh wand guile -c "'(use-modules (guix config))'"

It can be useful to add a dedicated user account on the remote for
offloading to avoid clobbering your regular profile.

Hope this helps,
Marius
