From 4c5ea6af7385064575531b1572c9bebf999b005d Mon Sep 17 00:00:00 2001 From: Vagrant Cascadian Date: Wed, 2 Aug 2017 17:03:03 -0400 Subject: reproducible: Add two new armhf builders (jtk1b, jtx1b). Temporarily disable two armhf build nodes (jtk1a down, ff64a too slow). Add an additional build job, as the new machines have more capacity than the old.
