Description
Right now, there's a gotcha in the Rust Backporting docs where a maintainer backporting a post-RVA23 Rust toolchain (i.e., anything from 26.04+) to any pre-RVA23 Ubuntu release (i.e., anything earlier than 26.04) will produce a RISC-V Rust toolchain which tries to use features not supported by pre-RVA23 RISC-V systems.
This addition explains to maintainers how to ensure this is dealt with.
These changes have been practically tested; they have been verified to produce a valid pre-RVA23 toolchain when following the steps.
