DeepSeek-V4-Flash acting as my Linux sysadmin

I'm very happy with some Linux admin tasks I'm throwing at a locally running DeepSeek. My request was simple, check why 'samples' folder is taking more and more space on one of the machines on my LAN, is this a syncthing problem? OpenCode used DeepSeek-V4-Flash to investigate, it logged into that remote machine, executed diagnostic code it wrote, found that syncthing is indeed still syncing the folder it shouldn't be syncing, and it correctly executed a syncthing API call to remove the folder from the pool. All in one go. You only see the end of the conversation. I was impressed. In another exercise it correctly investigated apt-get upgrade problem, pinning it down to insufficient /boot partition size, and then guiding me to remove unnecessary kernels from the partition (and offering help in resizing the partition if I want to!). This kind of stuff is what I used to use Claude Code + frontier models for. (Yes, I can execute such tasks manually too before you ask. But it's faster to investigate using AI if you have _many_ machines on your LAN.) But now local AI seems to be sufficient. My config: DeepSeek-V4-Flash on DGX Spark, served from llama-server.cpp. Interfacing via OpenCode. Can share config files if anyone's interested.
