On the home page there is a link to the release candidate: drupal-4.3.0-rc.tgz

On the downloads page the link to release candidate is: drupal-4.3.0-rc.tar.gz

This caught me out recently http://drupal.org/node/view/2388, when I had both rc.

I don't see the need for the duplication (it is bad, right?). How are these files generated - are they guarenteed to be in sync?
