I never update packages on servers, I build a new image/instance, test it, and replace the server. I have six or so servers, all of them configured differently. Not completely differently; they share some configuration. But not very similarly either. They're pets. They have a lot of state. Backups are running, but I certainly don't want to reinstall them. Despite being pets, I still want to do as little work to manage them as I possibly can. NixOS is great in this scenario.
