Wow, don't recall the full context here. But at least with Paul's container patchset, a subsystem can only be mounted once. So if the nsproxy container subsystem is always mounted by itself, then you cannot remount it to bind it with cpusets. > IMO that may be a good feature by itself, which makes it convenient to > bind different containers to different cpusets.
