synopsis: Option `allowed-uris` can now match whole schemes in URIs without slashes
prs: 9547
---
If a scheme, such as `github:` is specified in the `allowed-uris` option, all URIs starting with `github:` are allowed.
Previously this only worked for schemes whose URIs used the `://` syntax.

of the environment (typically, a few hundred kilobyte).
- [`preferLocalBuild`]{#adv-attr-preferLocalBuild}\
If this attribute is set to `true` and [distributed building is
enabled](../advanced-topics/distributed-builds.md), then, if
possible, the derivation will be built locally instead of forwarded
to a remote machine. This is appropriate for trivial builders
where the cost of doing a download or remote build would exceed
the cost of building locally.
If this attribute is set to `true` and [distributed building is enabled](../advanced-topics/distributed-builds.md), then, if possible, the derivation will be built locally instead of being forwarded to a remote machine.
This is useful for derivations that are cheapest to build locally.
- [`allowSubstitutes`]{#adv-attr-allowSubstitutes}\
If this attribute is set to `false`, then Nix will always build this
derivation; it will not try to substitute its outputs. This is
useful for very trivial derivations (such as `writeText` in Nixpkgs)
that are cheaper to build than to substitute from a binary cache.
If this attribute is set to `false`, then Nix will always build this derivation (locally or remotely); it will not try to substitute its outputs.
This is useful for derivations that are cheaper to build than to substitute.
You may disable the effects of this attibute by enabling the
`always-allow-substitutes` configuration option in Nix.
This attribute can be ignored by setting [`always-allow-substitutes`](@docroot@/command-ref/conf-file.md#conf-always-allow-substitutes) to `true`.
> **Note**
>
> You need to have a builder configured which satisfies the
> derivation’s `system` attribute, since the derivation cannot be
> substituted. Thus it is usually a good idea to align `system` with
> `builtins.currentSystem` when setting `allowSubstitutes` to
> `false`. For most trivial derivations this should be the case.
> If set to `false`, the [`builder`](./derivations.md#attr-builder) should be able to run on the system type specified in the [`system` attribute](./derivations.md#attr-system), since the derivation cannot be substituted.
