Hi Nathan,
I drafted a c2c standalone teuthology test[0]. Would you be so kind as to push it to
GitHub on my behalf so that it builds the corresponding packages? I'm sorry to bother
you with this but I don't know if there is another way to build the packages and tell
teuthology to get them.
Cheers

The reason I gave you one is because I know nothing about your environment, the
topology, the system, or the load you're running. The many commands in that script
should give me enough information such that I don't come back a 2nd time asking you to
rerun something because I needed more information.
