Well, I know the subject's not too clear, so let me try to explain. (Also, my 'e' key doesn't work too wll.) I made a union containing three directories, all read-only like this (not the actual directory names, but this is for clarity):

mount -t unionfs -o ro,dirs=/test/ro/ro1:/test/ro/ro2:/test/ro/ro2 union.ro /test/union.ro/rodata

When I try to make another union, as shown below, I can't see any of the rodata, although the rodata directory shows up in /test/union.rw and the data in /test/ro/ro? shows up in /test/union.ro/rodata.

mount -t unionfs -o dirs=/test/rw=rw:/test/union.ro=ro,delete=whiteout union.rw /test/union.rw

I, later, wondered about bind mounting the union.ro to bind.ro and putting that in the union.rw but no data shows up from the union in the bind mount. For example, if I bind mount the union.ro as shown below, I can still see the data in union.ro but not in bind.ro.

mount -o bind /test/union.ro /test/bind.ro

Am I doing something wrong? Is this just some strange bug that I happened upon whilst being weird?
