And they aren't --- the kernel does not make any difference between an ordinary mount and a bind mount. See for example http://karelzak.blogspot.com/2011/04/bind-mounts-mtab-and-read-only.html for a nice explanation. Consequently, all userspace apps which relied on this "difference" were broken to begin with, and need to be fixed. The only issue is that before F15 this was not obvious. F15 featured a new version of gnulib which basically made /etc/mtab obsolete (as far as I understood). Since F15 /etc/mtab is just a symlink to /proc/self/mounts, and I guess it will probably be removed altogether in the future. Also, this is not just for Fedora, but rather *all* Linux distributions which feature the recent gnulib. And it seems that everybody decided to go for the "mtab is a symlink" behavior for the time being. So if your favorite userspace app misbehaves because of this, file a bug against it and persuade the relevant devs to fix it.
