So this becomes a matter of just guessing what should be in root for the benefit of a possible future project or eliminating the root/usr mount point distinction (because we decide we can't guess, so we logically move everything by removing the distinction). As Jim said, the work to move a library (or most anything) from /usr to / is pretty trivial. We should move things as needed (because I don't do well as "The Great Carnack" (as in Johney Carson)). Its unfortunate that your students were deferred due to an unknown and untried process (but is completely understandable). It is part of the start-up cost of OpenSolaris. Most of what must function before /usr is mounted is pretty static, the notable exception is SMF and the SMF project team is well aware of the restrictions. If your students were just experimenting, they can certainly do the move themselves. If the experiment were to result in a project intended to integrate into the trunk, the move could have been proposed at that time. Prior to that, the students would really need to contact the SMF team for review and "buy in". This team would have known the relative simplicity of orchistrating the move. - jek3
