Here's a big shout out to TRS80 a.k.a James who installed Zenoss on Debian recently and then  published  the build instructions to the Zenoss forums. James writes:

"So I saw Zenoss linked from slashdot, and thought I'd give it a shot, having recently tried Zabbix and OpenNMS and finding neither was much good. So I downloaded it and noticed that it came with a whole bunch of third-party packages. Most of them were already available as Debian so I had a shot at installing Zenoss using them instead. I seem to have been successful, so here's how I did it...."

This is a beautiful thing, we supply our source code so you can compile on virtually any platform you choose. However, not everyone has the tech chops that James has, so in the future we hope to provide more binaries supporting Debian, and other Linux distributions in the mean time,  make is our friend...
