You can't do that. You could manage different perms for different
hosts (i.e. /usr is rw for host A and /usr is ro for host B), but
you can't mix perms for subdirectories within a mount to the
The reason is that the file handles passed to nfsd could then
be trivially faked to gain rw access on a ro-exported subdirectory.
For example, if you export /usr read-only and /usr/local read-write,
you can then construct an NFS request using /usr/local's mount point
but with a file handle that represents a file in /usr, and then be
able to write to that file. This is because the file handle
representing file X will be almost identical no matter which mount
point X is accessed relative to.
