that is available as a Facter fact, here you go:
% mc-facts lsbdistdescription
CentOS release 5.2 (Final) found 1 times
CentOS release 5.3 (Final) found 5 times
CentOS release 5.4 (Final) found 34 times
Finished processing 40 hosts in 5001.69 ms
run it with -v and you get a list of hosts matching, if you wanted to just find
the 5.2 you could:
% mc-find-hosts -W lsbdistdescription=/5.2/
xen6.my.net
If I just want to update 'httpd' package on those machines:
% mc-package -W lsbdistdescription=/5.2/ update httpd
Look at this video: http://www.youtube.com/ripienaar#p/a/u/4/kNvoQCpJ1V4 that's
exim queues and management
exposed over mcollective and centrally managed.

yeah, and audited centrally etc.

can't imagine that, at least if some other tool provide a transaction aware
layer sure, but it's an incredibly complex
task and probably varies per environment. Sure you could code rollbacks by
calling your package management tool in a
way that would trigger that. Certainly I do not believe something that just
calls remote procedures could do
rollbacks on your behalf.
