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