Managing 30+ machines with NixOS in a single unified config, currently sitting at a total of around 17k lines of nix code.
In other words, I have put a lot of time into this. It was a very steep learning curve, but it’s paid for itself multiple times over by now.
For “newcomers”, my observations can be boiled down to this: if you only manage one machine, it’s not worth it. Maaaaaybe give home-manager a try and see if you like it.
Situation is probably different with things like Silverblue (IMO throwing those kinds of distros in with Guix and NixOS is a bit misleading - very different philosophy and user experience), but I can only talk about Nix here.
With Nix, the real benefit comes once you handle multiple machines. Identical or similar configurations get combined or parametrized. Config values set for Host A can be reused and decisions be made automatically based on it in Host B, for example:
- all hosts know my SSH pub keys from first boot, without ever having to configure anything in any of them
- my NAS IP is set once, all hosts requiring NAS access just reuse it implicitly
- creating new proxmox VMs just means adding, on average, 10 lines of nix config (saying: your ID will be this, you will run that service) and a single command, because the heavy lifting and configuring has already been done, once -…
I have never used Tailscale. I have also Jever seen anyone in the wild recommend it and explain what exactly the use-case is beyond plain, old, reliable, open source WireGuard.
So yeah, agreed.
Also I have been hosting Jellyfin publicly accessible for years with zero issues, so idk… I also dint k ow what the “you have to use Tailscale for jellyfin” people are doing with TVs/Firesticks/… in hotels, airbnbs,…
