Ever since the introduction of pid namespaces, procfs has had very implicit behaviour surrounding them (the pidns used by a procfs mount is auto-selected based on the mounting process's active pidns, and the pidns itself is basically hidden once the mount has been constructed).

I like it. I think this will be very useful! Fwiw, I think sysfs could probably use the same treatment. It should probably gain a pidns & netns mount option and the ioctls to get those out of sysfs so you know where that sysfs belongs. Thoughts?
