hi guys,
I had to disable ccache on queensnake, all builds are fine right now. Let's see how it goes.
due OS migration on queensnake (scientific linux -> centos -> rocky linux) I think it's time to decommission the queensnake and request a new animal for a new server, maybe.

queensnake's seen repeated cycles of unexplainable build failures.
I wonder if it's using a bogus ccache version, or if the machine
itself is flaky.
