I'll skip past the manners and etiquette discussion for fear of turning
this into a bike shed thread; for the most part we're all usually pretty
polite here.  Having just moved to the Twin Cities (read: southern Canada),
I now suspect we have a lot of Canadian developers.  :) I can point to a
few other open source communities for comparison if anyone thinks we're
uncivil at times.  Having gotten that out of the way...

I think Richard's test probably more models what you'd normally see in this
kind of setup.  RHEL or SLED are most likely the majority of Linux servers
distributions used in a company where you'd be setting up clustering.  That
being said, my experience with Red Hat's cluster suite has taught me that
it's a _very_ difficult environment to get setup correctly even with Red
Hat's documentation and plenty of forum help.  Especially if you try to be
clever and customize your environment at all. Red Hat also has so many
upsteam, downstream and backported patches mixed together in any package
release that those packages might as well be considered another product all
together.  Nothing they release is even close to the original upstream
'vanilla' release.

However, having a clean working virtual machine base build as a starting
point for people trying to get this up and running on other distributions
would probably be very helpful for them and lower the mailing list volume.
Peace and Blessings,
