Export a file system with write permissions

Hi,

Is there a way we can export a file system with write permissions for only one user.

For eg. we have many users on the network, but only user2 should have write permissions on the exported file system and for others it should be read-only.

On AIX and *BSD is possible, let's say :

These are just examples I have found in the net.

I'm getting invalid options error.
Please point me to the source, so that I can read and continue.

thanks.

Here are two links I've found - No1 and No2; Actually, the thing that you want may not be possible at all, regardless of the OS type, I didn't find absolute proof that this will work on AIX either. Sorry if I misled you.

Seems like it.
Anyway, thanks for the effort

will this theory be applicable for ZFS?

I'm not sure, it may depend on the certain OS implementation, for example FreeBSD has added experimental support for ZFS, you have to check the manuals.

I don't think ZFS will do anything for you, the permissions are handled by NFS.
In the manpage exports, there is a section (looking at the linux manpage) about user id mapping. When you have the same userid's on both hosts. The permissions are inherited from the server to the client (that is at least possible, may differ on different OS-es)
So when you have the permissions right on the server (user2 rw, rest ro) you will have the same rights on the client.
