Subject Re: Karaf rpm distribution?
Date Thu, 22 Sep 2011 16:06:27 GMT
Hi Mike, I don't really know anything about JeOS.  It sounds interesting, but I use CentOS
almost exclusively.  

What you're talking about sounds a lot like Anaconda, though I doubt that Anaconda exists
on Debian platforms?  

As for VMWare, I really don't know too much about their products either.  XenServer did the
trick for me and I stuck with that.

Sorry I can't provide more info!
