In trying to rebuild the radicle 1.1.0 version now (2025-02-26), some months after 1.1.0 has been released, I see in my pipelines that the cargo install cargo-zigbuild@0.19.3 instruction is now failing.

This is because home@0.5.11 has been released and this patch version bump requires a newer version of rust (1.81) (0.5.9 was ok with 1.80). See https://github.com/rust-lang/cargo/issues/14944 for more details.

Adding --locked here prevents this issue from happening in the future.

Importantly: newer versions of other crates being picked up by cargo here means the build isn’t bit-for-bit reproducible.

The error itself is:
