Something to think about before attempting to centrally manage, your
systems actually have to be centrally manageable -- that doesn't happen
automatically and requires extra work.
this is why i never update. i would rather build a new image and
deploy it to the thousands of servers than worry about updates. be it
an openssh security notice, or new ntp configuration, for me it is
easier to rebuild servers than update config files.
For that matter, imaging is a bad way to go about handling this, you'd
be better served by setting up something like Puppet or Chef and have
them handle configuration management for you centrally, along with
necessary software packages.
