This is issued from computer A (abyayala) to computer B (shadownet).

address@hidden ~$ ssh shadownet env |grep GUILE_
GUILE_LOAD_COMPILED_PATH=/gnu/store/m91mxi586pi2qshzys9zfsmzij8nf547-profile/lib/guile/2.2/site-ccache:/gnu/store/m91mxi586pi2qshzys9zfsmzij8nf547-profile/share/guile/site/2.2
GUILE_LOAD_PATH=/gnu/store/m91mxi586pi2qshzys9zfsmzij8nf547-profile/share/guile/site/2.2

I would have to put some ssh private keys on there or
configure sshd in a different way to issue this locally
on computer B.
