Hmm, how did I miss this?

Right...that makes sense now that I look at the code again.

Wait...I probably even experienced this breakage after running `guix
pull' on the Hurd but failed to notice its cause, the missing guix/*.go,
and ascribed it to "something" being broken on Hurd.  So the good news
is that we'll most probably have guix pull work on the Hurd after fixing
this!

--8<---------------cut here---------------start------------->8---
             (cute partition <> files)
             (lambda (regex)
               (cute string-match regex <>))
             (cute string-append "^gnu/packages/" <>)
--8<---------------cut here---------------end--------------->8---

it still has the "gnu/packages" directory name hardcoded here.  (I even
believe this was kind-of intentional, meaning not to split-up builds of
other directories...).  The result is, of course, that partition always
produces an empty result for any '("guix/foo.scm") files!

It is fixed by doing

--8<---------------cut here---------------start------------->8---
             (cute string-append "^" directory "/" <>)
--8<---------------cut here---------------end--------------->8---

i.e., also splitting guix/ 26 ways.

Thank you for looking into and taking care of this mess I made, sorry!

Using the attached patch, I ran

--8<---------------cut here---------------start------------->8---
$ guix pull --branch=master --url=$PWD

Ah, nice that guix works too for me too now

$ make as-derivation
