The new derivation should evaluate only if the old derivation does.
Sadly this means that the old derivation cannot depend on the new one
any more, which was used by xorgserver on Darwin. But this is not a
problem as `overrideAttrs` can (and should) usually be used instead.
This change allowed catching an invalid `meta.platforms` in the linux_rpi
kernels, which use `overrideDerivation`.
The trailing `'` was included by mistake and is not supposed
to be there:
```ShellSession
$ base64 -w0 /etc/ssh/ssh_host_ed25519_key.pub
c3NoLWVkMjU1MTkgQUFBQUMzTnphQzFsWkRJMU5URTVBQUFBSUpCV2N4Yi9CbGFxdDFhdU90RStGOFFVV3JVb3RpQzVxQkorVXVFV2RWQ2Igcm9vdEBuaXhvcwo=
```
The reason it did not cause issues before is because
Nix ignores everything after the `=`:
3dbf9b5af5/src/libutil/util.cc (L1539-L1540)
… so it's harmless but still worth fixing.
- Extensive documentation in NixOS manual
- Deterministic mode that fixes various identifiers relative to disk
partitions and filesystems in ext4 case
- UEFI variable recording
Building the nixpkgs manual currently triggers a bunch of deprecation
warnings, because every attribute in `lib` is evaluated to see if it's
an attrset to generate locations for.
Instead, share the lib subsets to include in the documentation
between `lib-function-docs` and `lib-function-locations` so they can
coordinate.
Also generate the list of sections instead of duplicating it in
`library.xml`.
Presenting an example with a patch (without even providing that patch!) is not ideal. Since `npm pack` now obeys `--ignore-scripts`, we can use that instead.
Avoids confusion: `vim-full`'s build-time features are configurable, but both
`vim` and `vim-full` are *customizable* (in the sense of user configuration).
If all the docs are auto-generated, it should be easier to convert
them to Commonmark.

The nixpkgs manual contains references to both sri hash and explicit
sha256 attributes. This is at best confusing to new users. Since the
final destination is exclusive use of sri hashes, see nixos/rfcs#131,
might as well push new users in that direction gently.
Notable exceptions to sri hash support are builtins.fetchTarball,
cataclysm-dda, coq, dockerTools.pullimage, elixir.override, and
fetchCrate. None, other than builtins.fetchTarball, are fundamentally
incompatible, but all currently accept explicit sha256 attributes as
input. Because adding backwards compatibility is out of scope for this
change, they have been left intact, but migration to sri format has been
made for any using old hash formats.
All hashes have been manually tested to be accurate, and updates were
only made for missing upstream artefacts or bugs.
Promote the `maintainers = with maintainers; [ ]` syntax as that is most common
in nixpkgs, and remove the `nix-env` example which doesn't work like that anymore.
The `sparseCheckout` argument allows the user to specify directories or
patterns of files, which Git uses to filter files it should check-out.
Git expects a multi-line string on stdin ("newline-delimited list", see
`git-sparse-checkout(1)`), but within nixpkgs it is more consistent to
use a list of strings instead. The list elements are joined to a
multi-line string only before passing it to the builder script.
A deprecation warning is emitted if a (multi-line) string is passed to
`sparseCheckout`, but for the time being it is still accepted.
It gives a warning on the lazy-trees branch of Nix
(NixOS/nix#6530)
one of these was also giving me an error (the one in lib/trivial probably)

A tricky thing about FreeBSD is that there is no stable ABI across
versions. That means that putting in the version as part of the config
string is paramount.
We have a parsed represenation that separates name versus version to
accomplish this. We include FreeBSD versions 12 and 13 to demonstrate
how it works.
