[9fans] strange behaviour of bind

[paurea@dei.inf.uc3m.es]

I have encountered a behaviour in bind (well, actually in the fs) which
I find inconsistent. I may not be a bug, but it is counter intuitive.
Say you have two directories free_space and non_writable.
If you write:
bind -bc free_space non_writable 

You add space to non_writable. Everything works fine. free_space is before
non_writable in non_writable. If you create a file in non_writable you
are actually creating int in free_space.

bind -ac non_writable2 free_space2

non_writable2 is after free_space2 in free_space2. You should be able to
write in free_space. *you can't*. Even stranger:

bind -ac fspace1 fspace2

Any file in fspace2 supersedes any file in fspace1 with the same name,
but if you create a file in fspace2 it is actually created *in fspace1*!!!???.
fspace1 is *after* fspace2 for already existing files,
but it is *before* when you create new ones.

I find this weird and counter intuitive. It also seems to contradict
the manual page.  Is there any reason for this?. Is there something
I am not getting?.
