Linux seems to have done that pretty well without getting all bloated (unlike early Solaris releases, I can't speak to the later ones). Linux is just more mature, has had more people working on it (which is both a good and a bad thing). And didn't have Sun's stick in the mud approach to compat that made things like /proc in Solaris way way way less useful than Linux' /proc. So it's really hard to say.
