Great! Over the past 2 years I've found it worth migrating more and more of my infra to NixOS. Now my laptop, media server, router, and VPSs all run NixOS. From Debian+cfgmgmt to NixOS I've gone from a feeling of dread that my machine wouldn't be rebuildable, to confidence they can. A build tool to construct a Linux machine conceptually makes more sense to me than taking a distro and repeatedly mutating it. NixOS's model is similar to React's: build the system/value you want, and NixOS will perform the diff/apply to your actual machine. The downsides are: * It doesn't look like an ordinary Linux machine. No FHS. * CLI tooling is a bit awkward. * Short support for stable releases. I see NixOS being suitable for rolling release, even in a production environment. NixOS's repo and your own repo can easily add multi-machine integration tests so NixOS machines can use familiar techniques like CI/CD/push-on-green.
