The above patches, hacks and questions are still relevant, but I've made some progress on the issue below. > There's also one problem probably within the Guix Build Coordinator > itself, after doing a few builds, it will just stop.

I tried disabling a few of the optional features plus unnecessary locks on the hurd [1], and with those changes I no longer see it just stop, which is great, as then builds just keep happening :) 1: https://git.cbaines.net/guix/build-coordinator/commit/guix-build-coordinator?id=b3733bca21de607fd7a70319e66e3ff49996a974 For the guix.cbaines.net build farm, I've now got an additional machine running two childhurd VM's, and I plan to scale this up to 7 or 8 in the coming days to see how far it's possible to get building things for the i586-gnu.
