OK, works exactly as expected. Got a big red error, just how I like them ;-)

Yup, more or less. It would be nice to be able to report something else than 0
or 1. To comply with directive, a 'threshold' should be added.

But I'm perhaps far from the concept of rudder.

At least, I have an information about system being up-to-date or not. Added with
a few packahe version check for critical packages (openssl, bind, ssh, ...), I
think we'll be able to get a start of what we need.

Lemme check this a couple hours more and I'll come back with more questions
about how to do this or that ;-)

Thanks for your help,
Julien
