These are helper programs that execute derivations for specified
system types (e.g. using QEMU to emulate another system type).
To use, set `external-builders`:
external-builders = [{"systems": ["aarch64-linux"], "program": "/path/to/external-builder.py"}]
The external builder gets one command line argument, the path to a JSON file containing all necessary information about the derivation:
{
"args": [...],
"builder": "/nix/store/kwcyvgdg98n98hqapaz8sw92pc2s78x6-bash-5.2p37/bin/bash",
"env": {
"HOME": "/homeless-shelter",
...
},
"realStoreDir": "/tmp/nix/nix/store",
"storeDir": "/nix/store",
"tmpDir": "/tmp/nix-shell.dzQ2hE/nix-build-patchelf-0.14.3.drv-46/build",
"tmpDirInSandbox": "/build"
}

Until these repos are potentially merged, this is good for dogfooding
alongside the experimental installer. It also uses the more official
`artifacts.nixos.org` endpoint to install stable releases now
More immediately though, we need a patch for the experimental installer
to really work in CI at all, and that hasn't landed in a tag yet. So,
this lets us use it right from `main`!
Introduce a new build option 'curl-s3-store' for the curl-based S3
implementation, separate from the existing AWS SDK-based 's3-store'.
The two options are mutually exclusive to avoid conflicts.
Users can enable the new implementation with:
-Dcurl-s3-store=enabled -Ds3-store=disabled
Add lightweight AWS credential resolution using AWS CRT (Common Runtime)
instead of the full AWS SDK. This provides credential management for the
upcoming curl-based S3 implementation.
Realisations are conceptually key-value pairs, mapping `DrvOutputs` (the
key) to information about that derivation output.
This separate the value type, which will be useful in maps, etc., where
we don't want to denormalize by including the key twice.
This matches similar changes for existing types:
| keyed | unkeyed |
|--------------------|------------------------|
| `ValidPathInfo` | `UnkeyedValidPathInfo` |
| `KeyedBuildResult` | `BuildResult` |
| `Realisation` | `UnkeyedRealisation` |
Best I can tell this was never supposed to be exposed to the user
and has been this way since 2.19.
2.18 did not expose this file to the user:
nix run nix/2.18-maintenance -- eval --expr "import <nix/derivation-internal.nix>"
error: getting status of '/__corepkgs__/derivation-internal.nix': No such file or directory

Move ParsedS3URL from s3.cc/.hh into dedicated s3-url.cc/.hh files.
This separates URL parsing utilities (which are protocol-agnostic) from
the AWS SDK-specific S3Helper implementation, making the code cleaner
and enabling reuse by future curl-based S3 implementation.
