I use NixOS for all my systems now, single config covers two servers, laptop, notebook and desktop.
Containers aren’t something to be afraid of, I’ve found nix + podman to be super easy to use / configure, so much it’s a copy / paste a config from another container with some small directory changes.
If you are not someone who likes using a terminal perhaps nix isn’t for you. I’ve found forcing the terminal & configuring via nix has given me much more insight into my machines / os than ever before. If you’ve got the time to mess with Nix I’d recommend it.
If that sounds like a bunch of effort and time to get something that may be easier via another method, I’d say Proxmox is the way to go.
Running through my config I’ve just noticed that I’ve got an IP conflict that I wasn’t aware of, but makes total sense right now 😅
I think I’d be more concerned if my hands were that small
