Motivation for this change
Resolves nix-community/nix-direnv#89. nix-direnv depends on nixUnstable for flakes support, but that causes it to print a warning unless your user is trusted or the
experimental-features
setting is enabled. Neither of these are desirable (note that settingexperimental-features
in nix.conf causes warnings on nixStable).Since flakes are experimental, this PR makes the default
nixStable
and optionally allowsnixUnstable
with a new flagenableFlakes
, prioritising a good experience for users not using experimental features.Things done
