What happens when you boot an old kernel after you've upgraded all of
your binaries to use the latest libc, which happens to use a new
'stat' syscall number?


In general, "new kernel with old <everything else>" is important to
make fork, but "old kernel with new <everything else>" isn't, nor is
it possible to do easily.
