> The first challenge that interested developers will run into is actually building that support. The kernel configuration process looks for the prerequisites on the build system and, if they are not present, silently disables the Rust options so that they will not even show in, for example, make menuconfig.
I've seen options (in older parts of the code, can't remember which) that display a line of informational text in the menu when the normal option is unselectable due to a non-adjacent thing. Perhaps that ought to be a generalised mechanism, because it could've saved me an hour or two of stumbling around trying to figure out how the LLVM LTO feature worked.
