IIRC, bind mounts were broken in the Filesystem RA until the
beginning of 2009. Take a look at this changeset (at
hg.linux-ha.org/agents) and the corresponding bugzilla for more
information:

Yes, I've noticed that, but since the version you're running is
rather old, couldn't find it of any use there either. If you take
a look at the changeset, you'll notice that bind mounts needed a
bit more fixing too :)

Good!
