Hello Guix!
Here’s what I get on my freshly booted system:

As you can see, this is not great.
This comes from the load-path expression in shepherd-*.scm:
--8<---------------cut here---------------start------------->8---
(eval-when
(expand load eval)
(set! %load-path
(cons "/gnu/store/8a49xjf71dxzj2j4vqh4gw840xv1shxg-module-import"
(append
(map
(lambda
(extension)
(string-append extension "/share/guile/site/"
(effective-version)))
(quote
()))
%load-path)))
(set! %load-compiled-path
(cons "/gnu/store/lfj61bg7bb0aypqwj47j2dqnwc9bvpiw-module-import-compiled"
(append
(map
(lambda
(extension)
(string-append extension "/lib/guile/"
(effective-version)
"/site-ccache"))
(quote
()))
%load-compiled-path))))
--8<---------------cut here---------------end--------------->8---
Problem is that every time you reconfigure, the load path grows. Seen
on an important machine (ahem…):
--8<---------------cut here---------------start------------->8---
# herd eval root '(length %load-path)'
Evaluating user expression (length %load-path).
