Re: [Debian-NYC] Fwd: Puppet presentation Wednesday Nov 18th.


They do record video. I can't promise the quality will meet your needs
though. However, let me try and give you some quick pointers.
(Assuming of course you are talking about cfengine2. cfengine3 is a
whole other story)

1) Puppet supports dependency graphs.
2) Puppet supports dependency graphs.
3) Puppet supports dependency graphs.
4) Puppet syntax to many(most) is easier to understand, and is
actually a true DSL. (Rather than a config file).
5) Puppet has built in cross platform support, and supports resource
abstaction. IE: The syntax to add a user is pretty much the same on
all supported platforms.

Here's a link with more details:

The biggest issue many folks had with cfengine2 was that you'd have to
multiple runs to get to the promised state, as you really had no way
of setting an order of precedence. Let me know if you need examples.

You may want to talk to a coworker of mine, Eric E. Moore, as he has
run cfengine2 in academic HPC environments, and has been a puppet user
for over a year now. He also gave a presentation, comparing and
contrasting cfengine2, puppet and cfengine3. (It was a while ago.. the
summary was, puppet is clearly better than cfenegine2. cfengine3 was
too new, to really compare to puppet, but was clearly better than
cfengine2 and addressed some of its biggest deficiencies.)

The one thing you may be addicted to with cfengine2 is the ability to
"edit" config files. Naively puppet can't do this and relies either on
OS tools, (e.g. useradd), pushing out files, and pushing out
templates. That said there is a third party add-on that gives you this
ability, but it really is an antithesis of the "puppet way",
