My initial thought was to stage IMA namespacing with just IMA-audit first, followed by either IMA-measurement or IMA-appraisal. This would allow us to get the basic IMA namespacing framework working and defer dealing with the securityfs related namespacing of the IMA policy and measurement list issues to later. By tying IMA namespacing to a securityfs ima/unshare file, we would need to address the securityfs issues first. Mimi
