name	args
storePath	path

This function allows you to define a dependency on an already existing store path. For example, the derivation attribute src = builtins.storePath /nix/store/f1d18v1y…-source causes the derivation to depend on the specified path, which must exist or be substitutable. Note that this differs from a plain path (e.g. src = /nix/store/f1d18v1y…-source) in that the latter causes the path to be copied again to the Nix store, resulting in a new path (e.g. /nix/store/ld01dnzc…-source-source).
