good, if I don't succeed with my upgrade, I'll try that.

Will the official hydra be on 16.03 or unstable?

I am upgrading to hydra 177bf25 on nixos 16.03 and it seems to work
except that hydra lost the ability to do distributed builds.  Has
something changed in this regard in hydra/nix/nixos?

In "journal -xe" log, I can see that hydra-queue-runner loads a build
into nix-daemon but then the build is stuck as queued forever.

I can't see any error messages from nix-daemon.  Is there a way to debug
nix-daemon in order to see, what is it doing?
