We want to make NFS share superblocks on a per-filesystem basis, rather than forcing it into a per-server basis. Cachefs may like the latter, but POSIX does not like a filesystem where inode numbers are not guaranteed to be unique. A unique per-server superblock also makes it hard to support features like failover onto replicated filesystems and/or migration of individual filesystems onto another server.
Cheers, Trond
