This is a flag that disables subversion keyword substitution.
Keyword substitution inserts metadata into the files being checked
out, and is therefore somewhat at odds with build reproducibility.
In particular, it can become a problem if you're trying to switch
between svn and a git export of the same thing (keyword substitutions
are normally not exported into git).
This allows for a less blanket approach than nuke-refs, targetting specific
references that we know we don't want rather than all references that we don't
know we want.
Because of bash 4.4 the semantics GLOBIGNORE changed.
This resulted in already compressed manpages to be compressed twice.
Also be careful about symlinks to fix #21777, e.g. the ledger example.

for the cargo commit which deprecated the registry.index key, and
implements this as a replacement. This gets rid of the error message
warning: custom registry support via the `registry.index` configuration is being removed, this functionality will not work in the future
This script is not needed anymore since "nix-prefetch-url --unpack
<url>" and "nix-prefetch-url -A foo.src" (where "foo.src" is a
fetchzip / fetchFromGitHub call) work fine.
This reverts commit 3d9017602b.
This didn't quite work as I had expected ... While it seemed okay at
first, it fails to propagate all the attributes it used to (notably
features). I'll revisit this later but reverting for now.
This adds a `dhallToNix` utility which compiles expression from the Dhall
configuration language to Nix using Nix's support for "import from derivation".
The main motivation of this compiler is to allow users to carve out small typed
subsets of Nix projects. Everything in the Dhall language (except `Double`s)
can be translated to Nix in this way, including functions.
This is required for Aarch64 since a lot of source tarballs ship with
outdated configure scripts that don't recognize aarch64. Simply
replacing the config.guess and config.sub with new versions from
upstream makes them build again.
This same approach is used by at least Buildroot and Fedora. In
principle this could be enabled for all architectures but
conditionalizing this on aarch64 avoids a mass rebuild on x86.
To achieve reproducible results, `cpio` archive members are added in
sorted order and inodes renumbered.
The `cpio-clean.pl` script is made obsolete by setting mtimes via
`touch` & using `cpio --reproducible`. Suggested by @dezgeg in
https://github.com/NixOS/nixpkgs/pull/21273#issuecomment-268116605.
Note that using `--reproducible` means that initial ramdisk creation now
requires at least `cpio` version 2.12 (released in 2015).
