Half the department I work for has a rich history when it comes to using OpenSource; we have nearly 1k hosts running Redhat (Fedora Core, CentOS, Debian). The other half of the company (the boring bearded mainframe people) cought the message later. They are"blue" so they are Novell lusers. "Aaaah, look at this nice YAST interface (with is non scriptable!)" Needless to say, this doesnt make Novell more popular with me, they have been bussy selling and implementing Suse on mainframes for year, and still i is no working. My advice: for community services, go with the mass, for niche market, go with your customer. Linux hosting is a commodity and not that many people have a mainframe at home...
However, I do think Novell is spoton when it comes to Xen and Redhat is missing the point.
Novell CTO defends 'unstable' Xen claims
"If you look at the Xen open source project, we have been the number two contributor during the past 10 months or so to that project. So we've kind of contributed most of the enterprise readiness for the Xen platform," Rex said.
