Ubuntu isn't the only Linux distribution offering easy automatic updates. It just does the best job of making them accessible. But if you take a few moments to add third-party repositories to your existing Linux install, you can get the same access to software, codecs, and OS updates, even if they're not part of your OS's default configuration. Here's how.

FEDORA 7
The quickest way to give Fedora 7 access to third-party stuff like multimedia codecs is to add the Livna repository, which is chock full of good stuff that isn't included in Fedora for purely legal reasons.

openSUSE
With openSUSE, adding repositories is arguably easier, but slightly more time consuming, because you have to enter them into openSUSE's administration utility, Yast, and then wait for them to sync.
