Ah Puppet isn't fragile and use Puppet quite a bit. While not perfect and
does have some bugs to work out. It works and works VERY well.

IMHO is much better than using pre-built images. With Puppet you can mix
and match a setup to be exactly what is specified. With images it's not as
simple, nor is keeping them updated.

Randy, I didn't mean to put down Puppet -- I think it is an excellent
tool and, in fact, we're trying to figure out if there can be some
synergy in using it together with our virtual appliance catalog
concept in AppLogic (still working on that).

On the rest -- copying VM images, we do agree :)

Best regards,
