At the client side, I don't see a problem with unioning NFS with other
FS. Kernel would still return all dirents of the union including those
from NFS and glibc readdir would be able to handle them appropriately.
Or am I missing something ?

At the server side, I can't see how NFS server could export a union.
I don't see how this could be sanely done with Union Mount. Erez, how
does Unionfs handle this ?

Is dis-allowing NFS-exporting of unions an option ?

Bharata.
