Operations checklist

This is a checklist of things that I think an operations team needs to get to a
pretty good state. By no means exhaustive, and a bit opinionated. What I think
is most important is at the top, but really should try to have all of them.

It is extremely important to have everything patched and up-to-date. This
includes all hardware, networking devices, you name it. You'll want to know
where and how to download the updates, how to install the updates, how to
back out of a bad update, and a rough estimate of how long an update
typically takes.
