At work, we have a weekly "knowledge sharing" meeting, yesterday I talked about the state of NixOS deployments tools.
I had to look at all the tools we currently have at hand before starting my own, so it made sense to share all what I found.
This is a real topic, it doesn't make much sense to use regular sysadmins tools like ansible / puppet / salt etc... on NixOS, we need specific tools, and there is currently a bunch of them, and it can be hard to decide which one to use.
