> It's more than a little funny that you disparage syscalls being Linux's stable interface, and then immediately praise Android, which only works because glibc isn't uniquely privileged the way you seem to want.

I never disparaged it; I said having it doesn't make it any more useful that OSs that don't, because the practical reality is that the kernel interface is narrow and highly technical, and a stable kernel binary interface has little to do with a user's day-to-day experience with an OS.

I daresay Android would still work pretty well even sans the kernel ABI stability, because the kernel is usually built from source, and if it isn't, then every Android source tree has kernel prebuilts for the kernel version shipping. I also never said nor implied glibc should be uniquely privileged; I think you have grossly misrepresented my comment.
