Linux is the de-facto OS on servers and mobile devices these days — but i was wondering about why it is so far ahead of other OSes like FreeBSD. As far as i know, FreeBSD has equal(better in some cases) performance, matches linux feature for feature, and has some of the greatest technologies : dtrace and ZFS. Why then, is Linux deployed on almost all servers, when other operating systems are a very compelling alternative?
