Canonical, the commercial organization behind the Ubuntu variant of the Debian distribution of Linux, said today that it has certified its Ubuntu 9.04 Server Edition to run on all 17 configurations of Hewlett-Packard's sixth-generation of ProLiant servers. As El Reg was crabbing about earlier this week, HP does not officially and fully support Ubuntu, as it does commercial Linux distributions from Red Hat and Novell. With the Red Hat Enterprise Linux and SUSE Linux Enterprise Server operating systems from those two respective vendors, HP has signed OEM deals that allow it to sell and front-end installation and technical support on behalf of those Linux disties, and the parties divvy up the money so they each get a cut of the action.
