8/31    is this cooler than say kickstart or FAI or whatever
        the current cool way to admin 10000 machines is?:

        \_ This seems to be focused on managing Xen VMs and require
           the host to have Xen already installed.  I'm still a fan
           of cfengine, though it won't do the initial install.  But
           I have setup kickstart to just install cfengine at the end
           of the install and have cfengine take care of most of the
           configurations.
           \_ Is it a lot of overhead to have Xen running on every machine?
           \_ Why not use System Imager?
              \_ System Imager, as it was last time I looked, is fine if
                 you're managing bunch of machines with *identical*
                 configurations.  cfengine is more flexible and can work
                 across multiple platforms as well.  Also changing a
                 configuration doesn't involve re-imaging the whole machine.
                 \_ System Imager is more flexible than that. You can
                    propagate just the changes. I much prefer SI to
                    Kickstart. If you want to use cfEngine on top of that
                    then fine, but cfEngine solves a (mostly) different
                    problem.
