I'm running 2.8.1 and have NoNetworkCommunication set to TRUE, however it ignores this and attempts to download the tests.
I also have a download cache on a different host in our lab and have specified this in the CacheDirectory value:
(i do actually specify a valid IP address)
However it does not attempt to talk to my http server, and instead tries to contact the phoronix mirrors.
Am I specifying this correctly? The documentation doesn't explictly say, however I suspect it's a bug.
