Poettering: Revisiting how we put together Linux systems

Oh, also, the sudden switch from LLVM to GCC. Switching to bash as the default shell. Changing their CIFS client. Breaking AFP support repeatedly in every release (did you know network search over AFP used to work?).

About the only highly backward compatible platforms out there are the moribund ones (Solaris, AIX, etc); FreeBSD, which makes a fair bit of effort but still breaks things occasionally; and Windows, which suffers greatly because it's so backward compatible.

Part of why OS X is so successful is *because* it breaks stuff, so it's free to change.
