Hello,

I'm not sur about what you want exactly, but is failry easy to add new
generic method, tailored for you need. Typically, if the "command"
methods doesn't do what you want, you could add your own, that handle
return code differently, and reports more preciselly what are the
packages not up to date. Actually, you could even add a
"is_system_up_to_date" method that is success if everything up to date,
error if not, BUT alse report all the packages not up to date.


There is some example here of generic methods I created for some demo:
https://gist.github.com/fanf/83ade79362bf51c44465
(I'm not a CFEngine expert at all (that's Nicolas and Benoit and
others), mainly used copy&paste from other generic methods :)

Don't hesitate if you want more information about how to add methods, or
if you have some specs for your need and don't know how to transform
them in methods.

Hope it helps,
