A symlink isn't a good idea as, iirc, the new udev still -reads- from
both /usr/lib/udev and /lib/udev ..  so it'd have two sources for the
exact same rules; could be an issue.

Given this, the way I see it all we need is a helper s.t. all installs
going forward put the rules into the right place according to the
installed udev (or maybe the installed virtual/device-manager) so that
ebuilds/packages dont need to worry about setting the paths
explicitly; and eventually as things progress all the rules in
/lib/udev will get cleaned out in favour of /usr/lib/udev ...  ?

We could always just forgo the helper and make all packages migrate
via a >=udev-186-r1 dep and setting the rules install paths explicitly
to /usr/lib/udev ...  the helper (to me) just makes this cleaner in
the ebuild..
