What were you trying to do that didn't work?

Packages in EPEL 8 and 9 that use the `%cargo_install` macro from rust-toolset and pass arguments to this macro fail to build on top of RHEL 8.10, RHEL 9.5, and in CentOS Stream 9.

The introduction of a subshell inside the `%cargo_install` macro implementation without explicitly passing through arguments causes a parsing failure for any passed arguments instead of them being passed through to `cargo`.

What is the impact of this issue to you?

Packages that need to pass arguments to `%cargo_install` fail to build. Personally, this affects many of my Rust packages in EPEL 8 (for example, rust-ripgrep and rust-tokei).

Please provide the package NVR for which the bug is seen:

rust-toolset-1.79.0-2.module+el8.10.0+22210+e7efad26 (for RHEL 8.10 / EPEL 8)

How reproducible is this bug?:

Always.

Steps to reproduce

1. fedpkg clone rust-tokei
2. cd rust-tokei
3. fedpkg switch-branch epel8
4. fedpkg mockbuild

Expected results

Arguments passed to `%cargo_install` are passed through to `cargo`.

Actual results

Arguments passed to `%cargo_install` fail the build due to a syntax error.
