Just a quick status update for that plague farm :

* The five armv7 nodes are running F21
* fist one is actually plague-server
* the 4 remaining ones are plague-builder nodes (connected now to
plague-server)

The reason why it takes more time than expected is that I had multiple
issues within centos infra, so not only focusing on that build farm.
It's cfgmgmt driven, so everything is done through something that can
be reproduced easily (if we need to extend/move)

Howard had to patch the plague packages to support armv7hl as
supported arches
I had to inspect and patch the plague-certhelper tool generating the
initial keys/certs, as it was defaulting to md5 as signature
algorithm, which doesn't verify on newer platform.
We'll send our patches "upstream" (if there is still an "upstream" for
plague :-p )

As Howard has more or less an initial armv7 tree for centos 7, we
decided it would be good to wait some extra days , and use his initial
tree/repo to build against, and not bootstrapping (again from scratch)
from f19/f20.

Once that is done, and that builders can build rpms, we'll open up to
people with instructions on how to use it (but basically that will
mean using the plague-client tool)

We also have to see how to import custom mock config files (and so
also targets, from a plague builder/server PoV) if those are needed
for specific packages

Cheers,
