Debian does, it is one of the reasons why I eventually made it my default choice for new long-term installations. Before I used Debian I tested SLS, Slackware, Yggdrasil and Redhat. I have run Caldera, Ubuntu and Mint as well as a bunch of special-purpose distributions (Raspbian, Puppy, LTSP on iOpeners, OpenWRT, etc.) but Debian is where it is at if it has to run for a long time spanning several upgrades.
