Unless I'm missing some trick, it's currently rather painful to mount a namespace /proc. You have to actually be in the pid namespace to mount the correct /proc instance, and you can't unmount the old /proc until you've mounted the new /proc. This means that you have to fork into the new pid namespace before you can finish setting it up.
Would it make sense to add a mount option to procfs to request a mount for pid_ns_for_children instead of task_active_pid_ns? --Andy -- Andy Lutomirski AMA Capital Management, LLC -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
