The distributor admits to taking the risk upon himself of distributing the binary images without the legal consent of Sun Microsystems. The SunOS code contains a VFS implementation, but does not contain a stacking vnode architecture (even though Rosental's stacking research was under the auspices of Sun Microsystems). I think you are reading too much into SunOS's "union" and "translucent" mount capabilities, which are less related to a stacking architecture than they are to special one-off implementation.
