I actually have some old patches that allow you to use an alternate root for all NFS versions; you'd do something like: /exports *(ro, root) /exports/foo *(rw) /exports/bar *(rw) and then a v2, v3, or v4 client would mount server:/foo or server:/bar. But that was just a fun project, it wasn't clear to me whether anyone wanted it particularly. Also, that didn't seem like a great user interface. I'd rather have something like rootpath=/exports foo *(rw) bar *(rw) Actually, as long as we were doing that I'd rather replace /etc/exports entirely; maybe do something like [nfsd] rootpath=/exports [export "foo"] clients=* options=rw [exports "bar"] clients=* options=rw And also use the same file for other nfsd parameters: [nfsd] versions=2,3,4,4.1 threads=8 rootpath=/exports [export "foo"] ... I don't know. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
