If this share is exported RO it should be mounted RO only. Unfortunately I
may mount a RO nfs share with RW option on a client (of course it does not
renders the share writeable) - but it will confuse unionfs. If you mount
your share explicitly RO you shouldn't get a permission denied...
We had the same problem with RO nfs root filesystem unioned with RW tempfs
on top of it. Hope I got the idea right what you intend to do :-))
Ciao,
