Are your worries just about replacing what is now a normal file with a
symlink, and the behavioral changes that come with that?  

I wonder if using a bind mount for the file would be more robust.  We
wouldn't, of course, be able to do it persistently, but I bet it would
be something we could count on udev to do for us.
