Yeah, I didn't like that either, but I've gotten used to it.
And I don't see those big changes anymore like I used to.  I still remember
manually following a HOWTO on upgrading my libc and moving from a.out
to ELF.  Such low level changes don't happen anymore in the kernel,
so the big leaps are not necessary.

The userspace API is really quite stable.  File I/O, libc, etc.
It's the guts of the kernel that is continually changing like lava
in a volcano :-)  And driver writers taste that.

I agree... it's a worthy compromise in the kernel too, I think.
But vendors are used to the OS manufacturer taking great pains to
be backward compatible.  Windows has some truly impressive backward
compatibility.
