I am not really constrained about mass storage (I mean, embedding a
Debian system on 1Gb is easy enough, and our systems does not have less
than 4Gb) but on bandwidth, so I guess I'm better to go with the
smallest (considering that no, python is not needed in our systems and
so, absent), cfengine3 according to you?

Also, I'm the only one at work which have ever heard of that kind
of tools, so I'm basically free to take whatever I want, and I've never
really cared about «coolness» of systems.
If I could only work with softwares that are older than me and simple
enough to not require updates every 2 months, I would be a happy coder.
