I use nixos on my homeserver, but I’m looking to switch it to Void as well. For me personally I just realized that it’s easier to set everything up with shell scripts and docker-compose. But that’s just my personal experience, by all means go ahead and try out nixos if you have the time. It has lots of unique features that you can’t replicate with “just a bunch of shell scripts”. This video does a great job of selling nixos. Maybe my favourite part of nixos is how they make “shortcuts” for a lot of common tasks. For example, setting up a letsencrypt ssl certificate for your webserver with autorenewal can be done in just two lines of config.
