I use nixops to manage my Urbit ship declaratively on a NixOS host.
I didn’t see any existing guides or references for doing so, and I largely improvised & cobbled things together based on my previous nixops derivations for servers, and the Urbit guides for cloud-hosting.
I thought a guide/reference might be helpful for other (existing and potential!) Urbit-ers who like NixOS. so I extracted some of my config and posted it here.
hope it is useful 🙏
