Hello Guix!

Good news: the new machine, bayfront.guixsd.org, is building Guix master
for x86_64/i686 with Cuirass⁰!

You can get substitutes from https://bayfront.guixsd.org; just authorize
its key (with ‘guix archive --authorize’), which is:

  (public-key 
   (ecc 
    (curve Ed25519)
    (q #8D156F295D24B0D9A86FA5741A840FF2D24F60F7B6C4134814AD55625971B394#)))

The machine was initially installed using substitutes from
hydra.gnu.org, but ever since it has been building stuff on its own (it
does not offload to any other machine at this point).  Thus it can be
used to check for reproducibility issues:

  guix challenge gdk-pixbuf \
    --substitute-urls="https://mirror.hydra.gnu.org https://bayfront.guixsd.org"

The machine runs GuixSD and its config is under version control:

  http://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/bayfront.scm

Currently Cuirass doesn’t expose much over HTTP¹ but hopefully we can
incrementally add the URLs that guix-hydra.el expects.

There are a few glitches to address, such as the fact that it builds
with max-jobs = 1 due to <https://bugs.gnu.org/20217>, but we’ll get
there.

Woohoo!  :-)
