Another solution (that looks cleaner) is to use mount --bind rather
than mount --rbind. That way, you don't keep the sub-mounts.

Currently you're using --rbind for directory. You should probably
use --rbind for plain and --bind for directory.
Agreed. This does look much cleaner, and also fits in with the
difference between the two options.
Does the attached patch for the 10mount script fix things for you?
Thanks,
Roger
