New build farm

New build farm

[Ricardo Wurmus]

Hi Guix,

in the past weeks I’ve restored some unused servers and turned them into
a secondary build farm.  It consists of 12 servers of which 11 are
currently in use (I broke one by accidentally deleting the bootloader,
oops).

The head of this build farm is available as <https://berlin.guixsd.org>.
It currently builds substitutes for x86_64.

Feel free to use it to satisfy your substitution needs.  You will have
to authorize the build farm’s signing key to use the substitutes:

--8<---------------cut here---------------start------------->8---
wget https://git.savannah.gnu.org/cgit/guix/maintenance.git/plain/hydra/keys/guix/berlin.guixsd.org-export.pub
sudo su
guix archive --authorize < berlin.guixsd.org-export.pub
exit
--8<---------------cut here---------------end--------------->8---

This build farm uses Cuirass, which is still much less convenient than
Hydra, but I hope that by using it in production we will have a better
understanding of what features we will need to implement next.

I should also say that I have previously observed truncation of
substitutes on slow connections and I suspect that there’s a problem
with the firewall settings at this site.  I’ll keep investigating this.

Thanks to Ludo and Andreas for the assistance with debugging the
configuration and setting up DNS, and to the MDC Berlin (the institute
where I spend most of the daylight hours of the week) for not only
letting me use the servers but also for hosting them.

Well, … I’m pretty sure that whoever runs their Twitter thing does not
know about this.  But I guess it would be fine :)

Big thanks to the Max Delbrück Center in Berlin for the machines and
hosting, and to you for tirelessly setting it up!

We know there are still limitations, in particular issues and missing
features in Cuirass, but I’m confident these will be addressed soon, and
this new build farm is a great step forward.

That there are so many GuixSD servers also gives us a great incentive to
implement remote reconfiguration!
