I would want to share a directory via NFS only read-only (data should not be corrupted).
However I would want the client to be able to use the mounted folder as if it was read write, as transparently as possible.
Basically I would want updates to go only one way, from server to client and not the other way around.
I don't really mind if my local updates are not 100% reliable (if they can be overriden by the reference server).
Is there a way ? With NFS options directly ? With some kind of mount trick ? I'm using Ubuntu 12.04 on both sides.
