Hah! Nicely done.

I think it's been a bit theoretical in the past, but that latest commit
is a great example of where we want to take UCC sysadmin/devops:
https://gitlab.ucc.asn.au/ucc-systems/ucc-ansible-soe/-/commit/8765f955d28963d41fe5d05a9140f57cf601aa9d

More and more UCC services are now under config management, which means
they can be set up, verified, repaired, replicated, tested or examined
by cloning a git repo like the above.

This lets people get involved at any level, share the learning, and
lets us be brave and try changes, confident that we can test them or
roll them back.

`mollitz` needed a little tweak, maybe other machines will need the same
thing later. It's a Sisyphean task to keep a page like:
https://wiki.ucc.asn.au/StandardOperatingEnvironment#Linux_Servers
current in every detail, so we can try to make our documentation a more
long-lasting overview and put some of the nitty-gritty into:
https://en.wikipedia.org/wiki/Infrastructure_as_code
