That is sort of a misguided attitude. If you run Ubuntu, you run plenty of systems stuff on Python. Also Perl and bash and C. If the piece of software works and doesn't require you to do extra shit to set it up, who cares what it's written in?

I can see caring about performance. A Python process will be more memory hungry than something hand coded in C. But for the rest of it, who gives a crap if t is packaged well. And if it's not, it's probably not worth using it at all.
