Canonical Goes It Alone with Unity

the new 2.6 development model was created specifically to address these sorts of problems.
I'm not saying that when RedHat implemented a feature they did so to deliberately lock users in to their flavor of Linux, but when the upstream developers went a different direction and didn't accept what they had already shipped to customers (and had companies like Oracle depend on) that's the effect that it had.

Whether competition has anything to do with any perceived changes is not clear to me, though. I suspect it has more to do with both the company and the communities it works in growing up.

RH's non-upstreamed tux patches caused me pain recently(ish). Turns out TUX added a flag to the open syscall named O_ATOMICOPEN. It used the next available O_ flag value after those used in upstream kernels. That flag was not upstreamed. Upstream then added a flag to open called O_CLOEXEC. They (of course) also used hte next available flag value.
So, new binaries which attempted to use O_CLOEXEC (even when they attempted to test for its existence before using it) would fail badly when it returned some completely unexpected random error value...
