Symlink works perfectly for /usr. I had some problems with simplinking
some parts of some root dirs, but big ones working just fine. I've ended
this practice because qtmoko had no smooth upgrade path and because of
expirements with glamo sd. Also i think it's probably better to have
single tree in fstab, not a graph of mounts until it's impossible to
avoid it like in case of mounting parts of / fs into chroot directory
(main reason bind mount appeared i think). Also you free to create,
rename or remove symlink, while bind-mount is sligly more difficult to
manage.
