Building a package with stable toolchain causes a dependency on rust-stable
I'm building a package with makeRustPlatform and buildRustPackage
If i do this with fenix.packages.${system}.stable - the built package ends up with a dependency on rust-stable (which is like 2gb+)
Doing the same with fenix.packages.${system}.stable.minimalToolchain or nightly minimal - the built package only depends on glibc and gcc-(version)-lib
I think that's a bug since there's no reason for the built binary to depend on the whole full toolchain. At least it should be documented in the readme.
Example:
/nix/store/qc88lqcvyn6vaniw01xw6yjbbs3hx9nr-lwmetrics-0.3.2 (built with stable)
