Probably only works for c strings

Padding with null chars is also possible

Converting longer paths to shorter relative ones should work

The replaceDependencies is the closest thing there is to replacing raw path to the nix store by another one in the nix-store, but beware that if the version changes from 0.4.0 to 0.4.0a this would cause a lot of issues.

I currently find that if I try to ask for recursive output on my configuration, I end up getting an absolutely inscrutable error about list index 0 is out of bounds in lib/generators.nix toPretty method.

the rust infra has this definition:

linkerForTarget = if shouldUseLLD pkgsTargetTarget.stdenv.targetPlatform
      && !pkgsTargetTarget.stdenv.cc.bintools.isLLVM # whether stdenv's linker is lld already
      then "${pkgsBuildTarget.llvmPackages.bintools}/bin/${pkgsTargetTarget.stdenv.cc.targetPrefix}ld.lld"
      else ccForTarget;

when cross compiling to arm-none-eabihf (target = "thumbv7em-none-eabihf") this ends up picking arm-none-eabi-gcc as CARGO_TARGET_*_LINKER which then fails due to being passed flags like --gc-sections, -flavor, --as-needed, eh-frame-hdr and similar.
