Or perhaps get a short hash of the hostname (generated once whenever hostname is set) and append the serial number you're implementing? It'd be way less human readable than your current proposal but it'd be unique "globally" (as long you don't have machines with the same hostname migrating containers between them), allowing the migrated namespaces to retain their unique identification across audit logs. It'd of course be way more costly than just using an atomic counter, but could be useful to anything that needs to refer to a namespace and could be migrated to another machine. What you think? Sounds too crazy? :) -- Aristeu -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
