It isn't supposed to. bind mounts make a clone if exactly what is there
right now at the time of the mount. Anything added later is new stuff
and does not and should not be bind mounted.
A common workaround is to do this:
point automount to /mychrootpath/home/...
ln -s /home -> /mychrootpath/home
So your automounter points at the chroot path from the main system, and
can of course access everything. The chroot knows nothing other than
when it asks for something, somehow it magically gets mounted. The main
system being able to see the chroot stuff can use a symlink to it just
fine and cause the automounter to work. What this doesn't solve is
trying to have two chroots work with an automounter. For that I can't
think of any solution.
It would be nice to have a bind mount that actively passes on new mounts
under the original one, but at this time I don't think we have any such
thing. Even rbind just recursively bind mounts every mount in a tree,
that are present when the rbind mount is performed but does nothing for
new mounts later on.
