Tim, the Hadoop labeled machines were not donated to ASF.  Minerva,  
Vesta, and a couple others (used now for buildbot) were donated to ASF.

I agree we should encourage folks to tie their linux builds to the  
"Ubuntu" label (which already exists), so both minerva and vesta get  

We should also encourage projects (spam-assasin, ftpserver, struts,  
vysper, xwork2) to move off of the Master hudson.zones.apache.org
