Hi,

some thoughts at the moment:

I'm using opscode chef at the moment, because my chef advised me to do so. The learning curve is steep, but after I got it, it helped me a lot.
I'm very fond of the extensible data discovery called "OHAI" available within chef. Every system is inventorized with a high grade of details and you can write data collection modules yourself. The data is available everywhere within chef and outside too, which is extremeley useful. You want a list of software packages from every machine? You want to search for a specific MAC address in your comany? You want an individual hardware report for all your machines? No problem. The data only waits to be searched.
This configuration management adds a considerable extra amount of resource overhead to the machines if regularly executed or as an additional service that has to run.
Personally I like the method to not use configuration management at all, but an approach to only use self created packages to reach the same goal: Nice video about an existing solution here: OSDC 2013 | Schlomo Schapiro: Configuration Management and Linux Packages (ENG) - YouTube
The piece of software behind the video is named YADT
What I dislike about chef is, that the platform support is limited to current mainstream linux distributions, which causes some older legacy distributions can not be managed with chef. What I also disklike are things that some extension package handles things in other ways the os doing it. E. g. the solid mysql-chef-gem(Yes it's based on ruby). sets up a system that allows multiple instances of mysql at the same machine and so setup of the mysql packages and the setup of the mysql-chef-way interferes with each other. That's why I'm not using the good chef-mysql extensions and stick to my own "recipes" here.

LEARN ABOUT DEBIAN

dh_installwm

DH_INSTALLWM(1) 						     Debhelper							   DH_INSTALLWM(1)

NAME

       dh_installwm - register a window manager

SYNOPSIS

       dh_installwm [debhelperoptions] [-n] [--priority=n] [wm...]

DESCRIPTION

       dh_installwm is a debhelper program that is responsible for generating the postinst and prerm commands that register a window manager with
       update-alternatives(8). The window manager's man page is also registered as a slave symlink (in v6 mode and up), if it is found in
       usr/share/man/man1/ in the package build directory.

FILES

       debian/package.wm
	   List window manager programs to register.

OPTIONS

       --priority=n
	   Set the priority of the window manager. Default is 20, which is too low for most window managers; see the Debian Policy document for
	   instructions on calculating the correct value.

       -n, --noscripts
	   Do not modify postinst/prerm scripts. Turns this command into a no-op.

       wm ...
	   Window manager programs to register.

NOTES

       Note that this command is not idempotent. dh_prep(1) should be called between invocations of this command. Otherwise, it may cause multiple
       instances of the same text to be added to maintainer scripts.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
