Environments are usefull for a lot of other stuff too:
For example the question "all non-virtual machine with ntp in my
environment" (because that is the same subnet by coincidence) is a good
choice to select peers (for non-virtual machine) or server (for virtual
machines).
Another example: "All machines with the recipe munin::client in the
'dev'-environment" is also a nice way to configure the munin-server.
Doing that with cookbooks or roles would certainly be possible: a role
"dev-munin-client" that inherits the role "munin-client" and then
search for all "dev-munin-client" to get the same as with the previous
example. Buts its not as nice I think.

Yes, I think I am part of the roles/environments-camp...

Have fun,

Arnold
