Yeah, I must have misremembered. Awkward.

In any case, the last thing such customers would want (if they existed) is a rebase from 2.6.18 to a 6.x kernel, or a toolchain upgrade for that matter. So what we do to current versions really does not matter to hypothetical commercial ia64 Linux users. > The only argument for continued support is as you described, the > argument from the commons, that the ecosystem as a whole benefits from > diversity of architectures.

Some of the variance/diversity isn't actually necessary, though. It's just that ia64 has some half-done stuff in the tools that no one bothered to fix, creating complexities elsewhere.
