Also the database and operating system support issues both seem to specifically Ghost ecosystem issues (JS as a language/ecosystem mostly doesn't care what DB you want to use and Node itself runs largely the same on every platform and probably doesn't even know the specific difference between Debian and Ubuntu). This seems a lot more a "Why is the Ghost ecosystem like this?" more than a JS ecosystem problem. (The answers to that question seem a lot easier to answer: small team, limited testing resources, and they focus on a paid SaaS platform as their business model to pay the bills and that likely comes first ahead of self-hoster's concerns/needs.)
