cache.lix.systems is quite slow, and doesn't contain anything but releases. It should only be enabled in nix upgrade-nix.

Reported by @arianvp

Corresponding issue to avoid adding cache.lix.systems to the default config in the installer: lix-project/lix-installer#64

Yeah, this should be an issue in the installer:

Lines 136 to 144 in lix-project/lix-installer@81a5d13
// Set up our substituters.
settings.insert(
"substituters".to_string(),
"https://cache.nixos.org https://cache.lix.systems".to_string(),
);
settings.insert(
"trusted-public-keys".to_string(),
"cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= cache.lix.systems:aBnZUw8zA7H35Cz2RyKFVs3H4PlGTLawyY5KRbvJR8o=".to_string()
);

Yeah, this should be an issue in the installer: https://git.lix.systems/lix-project/lix-installer/src/commit/81a5d136aaf6b81adc044171f1eb118220d99b9e/src/action/common/place_nix_configuration.rs#L136-L144

Well, but then we'll need to add the substituter to the setting when running nix upgrade-nix.

Well, but then we'll need to _add_ the substituter to the setting when running `nix upgrade-nix`.
