What is worse, and I don't see a way around it: Is that we don't have any callbacks to check where things are mounted. So we can't ensure the proper kind of filesystem is mounted in the right place. That is there is too much freedom in the mount apis to allow for reliable operation. > But at least the current patch reuses CLONE_NEWIPC for posix ipc, which > also seems to make sense. Sort of. I'm really annoyed with whoever did the posix mqueue support. Adding the magic syscall that has to know the internal mount instead of requiring the thing be mounted somewhere and just rejecting filedescriptors for the wrong sorts of files.
