I appreciate your comment and the humor in the situation since the original topic does everything the post you're glibly replying to requests. And so you just had to re-link it.

But it's still rolling-only code. And having to change it for every ubuntu release (even if per-release everything is targeted to the static version of rustc in Ubuntu) is silly since cargo editions won't save you. And since anyone actually compiling rust programs will have had to update their rustc constantly they'll have to do some containerization or something to compile the $version-written tool for $ubuntu-release-number.
