This is also - the flake reference that will be used by `nix profile upgrade`. - -* `uri`: The locked flake reference to which `originalUrl` resolved. - -* `attrPath`: The flake output attribute that provided this - package. Note that this is not necessarily the attribute that the - user specified, but the one resulting from applying the default - attribute paths and prefixes; for instance, `hello` might resolve to - `packages.x86_64-linux.hello` and the empty string to - `packages.x86_64-linux.default`. - -* `storePath`: The paths in the Nix store containing the package. - -* `active`: Whether the profile contains symlinks to the files of this - package. If set to false, the package is kept in the Nix store, but - is not "visible" in the profile's symlink tree. |
