nix-freeze-tree is a utility that walks a directory tree, and writes out Nix expressions which rebuild that tree. The generated expressions have two important properties: a) Each file in the tree is built by a separate fixed-output derivation, and b) Directories are built by derivations that symlink their contents recursively. If you are using nix copy to ship a derivation between nix stores, copying the derivation built by evaluating the output of nix-freeze-tree can reuse existing files in the destination store, as fixed-output derivations can be checked against a hash before copying.
