You must be using a personal branch, no?  It seems that =E2=80=98master=E2=
=80=99 cannot
be used natively on GNU/Hurd because we lack binaries under
gnu/packages/bootstrap/i586-gnu:

--8<---------------cut here---------------start------------->8---
$ guix build hello -s i586-gnu -n
guix build: error: could not find bootstrap binary 'tar' for system 'i586-g=
nu'
--8<---------------cut here---------------end--------------->8---

Manolis, I suppose we could cross-compile =E2=80=98bootstrap-tarballs=E2=80=
=99 to
i586-pc-gnu and get the mkdir, tar, etc. files from there?

Thanks,
Ludo=E2=80=99.
