Anthony, seems you forgot to push?

Reason I'm asking is that I've been seeing the following annoying
problem on master:

However `hostname` returns "<myhostname>.site" just fine, and I don't
understand why a user's local hostname should be causing 100% test
failures for block I/O tests in the first place...

Could someone please check on that?
