I was doing a number of unholy things at the time, effectively monkey-patching and syscall interception of some of the daemons for "seemed like a good idea at the time" reasons.
Also, sometimes, you just want to throw a tool on there to test something.
Today, I'd love to run stuff like tailscale for access to the control plane remotely.
Mostly, however? I did it because they said I couldn't.
