  60 ;; This is the hash for the empty file, and the reason it's relevant is not
  61 ;; the most obvious.
  62 ;;
  63 ;; The root of the problem is that Cargo keeps track of a file called
  64 ;; Cargo.lock, that contains the hash of the tarball source of each dependency.
  65 ;;
  66 ;; However, tarball sources aren't handled well by Guix because of the need to
  67 ;; patch shebangs in any helper scripts. This is why we use Cargo's vendoring
  68 ;; capabilities, where instead of the tarball, a directory is provided in its
  69 ;; place. (In the case of rustc, the source code already ships with vendored
  70 ;; dependencies, but crates built with cargo-build-system undergo vendoring
  71 ;; during the build.)
  72 ;;
  73 ;; To preserve the advantages of checksumming, vendored dependencies contain
  74 ;; a file called .cargo-checksum.json, which contains the hash of the tarball,
  75 ;; as well as the list of files in it, with the hash of each file.
  76 ;;
  77 ;; The patch-cargo-checksums phase of cargo-build-system runs after
  78 ;; any Guix-specific patches to the vendored dependencies and regenerates the
  79 ;; .cargo-checksum.json files, but it's hard to know the tarball checksum that
  80 ;; should be written to the file - and taking care of any unhandled edge case
  81 ;; would require rebuilding everything that depends on rust. This is why we lie,
  82 ;; and say that the tarball has the hash of an empty file. It's not a problem
  83 ;; because cargo-build-system removes the Cargo.lock file. We can't do that
  84 ;; for rustc because of a quirk of its build system, so we modify the lock file
  85 ;; to substitute the hash.
