It does *not* work for static setups - try to boot stock 3.3 on the root
fs with such a symlink and you've got a dangling symlink. Have fun
trying to bisect something with repeated jumps back and forth across the
point where such change goes in...
It will also do no good on setups like e.g. debian/stable, with stock
udev - you need to edit /lib/udev/rules.d/50-udev-default.rules to get
that link created, with quite a bit of interesting kludgery to avoid the
same kind of crap (i.e. setup breaking when you boot an older kernel).
