Regardless of if puppet is intended to manage multiple similar hosts, it is
still useful when you have a smaller number of unique hosts.
If every host is completely unique then you get one some benefits of puppet:
* you have a single place to review your configuration
* you can make changes without having to do it by hand
* puppet checks nothing has changed, and puts it back if something has
However, I bet that all your hosts are a *lot* more alike than you think:
* you probably use the same web server (apache, or so), and *mostly* have it
set up the same way on each machine, right?
* you probably use the same MTA on most machines
* you probably use the same log watching and checking stuff on 'em all
* you probably have similar needs for installing PHP and some extra PHP
modules, which are usually configured more or less the same.[1]
* you probably do a bunch of "install mysql, configure like this" stuff the
same on each host.
You forgot a biggy bonus of puppet, no matter what size you support. I
have several small ( as in 1-3) groups of very different machines,
and with puppet I can rebuild them very quickly on when they need to
be replaced or upgraded. doing it by hand takes most of a day or 2.
That's great! And what to do with various passwords, private keys and so
on? Should I put them in manifest?
