Would we not also need to support explicit assignment, in case someone has a preexisting image they want to match in a specific way? In that case we could start off without the dynamic allocation and add that later. It certainly would make testing a lot simpler if we had userns support sooner rather than later (at least in the case of netlink it appears to be quite a mess).
