By looking at the output of nix-info, I noticed a few things which I didn’t know how to interpret:
❯ nix-info -m
- system: `"x86_64-linux"`
- host os: `Linux 5.10.79, NixOS, 21.11 (Porcupine)`
- multi-user?: `yes`
- sandbox: `no`
- version: `nix-env (Nix) 2.4`
- channels(root): `"nixos-21.05.650.eaba7870ffc"`
- channels(asymmetric): `""`
- nixpkgs: `/nix/var/nix/profiles/per-user/root/channels/nixos`
sandbox
Why is sandbox off? I don’t change the default value (which is true):
❯ nixos-option -I nixos-config=/home/asymmetric/code/dotfiles/configuration.nix nix.useSandbox
Value:
true
Default:
true
# ...
appending to nix.nixPath
How would I go about changing the value of nixos-config in NIX_PATH, so that I don’t have to pass that -I flag above?
I would like to append/merge to the existing values, something like:
# flake.nix
nix = rec {
nixPath = nixPath ++ [ "nixos-config=/home/asymmetric/code/dotfiles/configuration.nix" ];
};
but this (obviously?) triggers infinite recursion.
channels
If I exclusively use flakes and the new experimental nix command, should I still care about channels? If not, can I simply delete the directory?
If I should still care, how can I ensure they are kept up to date with the version of nixpkgs in my flake?
