Facebook runs CentOS on its server fleet, and offers Fedora (and soon, CentOS) as supported Linux distributions on laptops and desktops. This is a recent development - we previously recommended Ubuntu LTS as a self-supported option, but found that switching to Fedora (and officially supporting it) allows for not only reusing the infrastructure already used in the server fleet (e.g. the pipeline for creating packages) but also to serve as an integration point for driving features into CentOS.

I'll also discuss how we manage the desktop fleet, and contrast it with how servers are managed.
