The 'there's one Linux' mantra has been a mix of both marketing hype and reality. Kinda. It is true there's one mainline kernel that most people fork from. However, the number of people that actually run that kernel stock, without mods, is tiny. Every distribution flavors the kernel, often extensively, as well as other parts of the system. These differences can be quite extensive when you look at it, and it is rare that all the changes make it back into the mainline kernel, though sometimes echos of them do (there's many SoCs that have forked kernels that never get their diffs back into kernel.org: god help you if you have to run on multiple of these from different vendors on a unified kernel version). So Linux really is a thick bush of somewhat similar code bases rather than a single code base that works everywhere. I think from a marketing perspective, we should play these difficulties up and not surrender the marketing point. But that's just me. Warner
