Multi-system administration with Func

Actually one easy example is doing an update of some package on all your systems, but only
where that service is a version with a known security risk. 

I can easily think of many tasks which I had to do fairly recently where a package like func
would have helped me. I can imagine though that if you don't have at least a few systems to
manage that setting up something like func is more a bother than a helper.
