Hello,
I think that bug 2491 at
https://bugzilla.kernel.org/show_bug.cgi?id=24912 sort of fell through
the cracks and I'm not sure as many people are aware of it as there
could be. This bug is that one can't mount bind mounts readonly but
can only remount them readonly which is insufficient for recursive
bind mounts and certain kinds of sandboxing. Also the bind mount fails
silenty without giving an error which is never a good idea.

Steven,
It's late now but I will look into this tomorrow and see if I can
trace the issue
and may be write a solution.
