Problem you are trying to solve

On Windows rustup currently uses junction points exclusively.

(note: that comment is wrong, user symlinks can be enabled by granting a single permission or more recently by enabling developer mode)

Junction points are always absolute which makes moving rustup (e.g. when setting up a dev drive) a more fraught process than it needs to be.

Solution you'd like

Use symlink_dir and only fallback to juncture points if that fails.
