Cargo install fails with musl rust

[arb000r]

Hey all,

Trying to build a docker image as per docs with clux/muslrust stable. However everytime results in

See this rust-lang/cargo#10781.

@LukeMathWalker Is there a way to add a flag to use unstable features (like -Z <unstable-feature> on cargo build) with cook?

[LukeMathWalker]

That'd be desirable, but it's not currently possible.

[louneskmt]

See #137.

@1saf: this is not an issue with cargo-chef, but rather an issue with cargo itself.

You have three workarounds:

• Use nightly: cargo +nightly -Z sparse-registry install cargo-chef;
• Use a prebuilt image that comes with cargo-chef already installed;
• Use CARGO_NET_GIT_FETCH_WITH_CLI=true cargo install cargo-chef to use an alternative method to fetch the registry.

The sparse-registry should solve this problem for good, but it's not stable yet.
