So I tried to follow some tutorial about flakes, but it seems these are extra-experimental still.
I am using NixOS 23.11 with Nix 2.18.1 in a VM (those are the most recent stable versions, right?).
Trying around I already found out that instead of eg. nix flake update I have to use --extra-experimental-features two times to get this simple command:
nix --extra-experimental-features nix-command --extra-experimental-features flakes flake update
Searching the web I found several different things that people put into their /etc/nixos/configuration.nix to enable this globally, but none of those worked for me. I assume there is still a way to do this - can someone please tell me the correct syntax for Nix 2.18.1?
What makes things worse is that I cannot start playing around with home-manager and flakes, because home-manager switch flake . seems to use nix flake internally, which leads to errors instead of results.
Thank you very much!
nix.settings.extra-experimental-features = [ “nix-command” “flakes” ];seems to actually work in my setup.
And it’s nice to know that I can make do with one
--extra-experimental-featuresargument for several features at once.May I be so bold as to ask a follow-up question that doesn’t have much to do with this one?
What do I have to do to get Virtualbox Guest Additions to work on NixOS? Not having a shared clipboard is driving me crazy ;-)
Once again everything I found on the internet leads to errors during
sudo nixos rebuild. I hope it’s just another case of knowing the correct names for the actual packages or options to use.Can someone help me here?
Looking at the configuration options I think you want this line in
configuration.nix:virtualisation.virtualbox.guest.enable = true;Yes! That’s the correct way to write this, thank you! 😊
And it’s already set inside
/etc/nixos/hardware-configuration.nixafter installing inside a VM.I had an additional layer 8 problem - clipboard sharing doesn’t work until it’s enabled in the VirtualBox host , too 🙃
