Note - you're asking setup questions which have actually already been
done by the folks as OSU/OSL at my request. So, these decisions have
already been made - we actually already have the box ready to go and
offer accounts to the people who will deploy codespeed and get the
benchmarks going.

This is already done. We have hardware level Raid 5

I'll leave that to you guys to decide. If you want it shut off, I need
to contact OSU/OSL to have it done.

This is up to the team. Currently, I have root and 1 user, and Fijal
has an account.

Benchmarking and code coverage only. This is not a general shell
account box for users. That's not how I sold it to HP who donated the

This server is for benchmarking CPython, PyPy and Jython and
potentially running detailed code coverage reports. Until we have that
done and in place, I can not in good conscience discuss allowing any
other users on the box for general jobs and work.

We should not be using virtualization to generate benchmark numbers;
hypervisors are lying bastards :)

Deployment is done. We need code.
