Longtime Linux+Unix user here too, I'm in the same boat, and it's been stunning what it can do.

A few days ago we were having networking problems, and while I was flipping over to my cell hotspot to see if it was "us or them" having the problem, a coworker asked claude to diagnose it. It determined the issue was "a bad peering connection in IX-Denver between our ISP and Fastly and the ISP needs to withdraw that advertisement." That sounded plausible to me, I happened to know that both Fastly and our ISP peered at IX-Denver. That night I reached out to the ISP and asked them if that's what happened and they confirmed it. In the time it took me to mess around with my hotspot, claude was doing traceroutes, using looking glasses, looking at ASN peering databases...

It is REALLY good at automating things via scripts. Right now I have it building a script to run our Kafka rolling updates process. And it did a better job than I did at updating the Ansible YML files that control it.

I've been getting ready to switch over to NixOS, and Claude is amazing at managing the nix config. It even packaged the "git butler CLI" tool for me; NixOS only had the GUI available.

I'm getting into the habit of every few days asking it: "Here is the syslog from my production fleet, review it for security problems and come up with the top 5 actionable steps I can take to improve." That's what identified the kafka config changes leading to the rolling update above, for example.
