Review: The Linux Programming Interface

I think this is your only legitimate complaint. Why not make a fix so the "abstract name space" is mounted under a permanent name. Then everything is in a predictable place in the filesystem, and you have all the HUGE advantages that they are in the same namespace you can search with existing tools.

/proc is full of files that used to be "namespaces" (actaully various kernel calls and tools that peeked into kernel memory maps). I think it is pretty obvious that /proc is VASTLY superior to the old api, in that it is discoverable and many more tools are written to use it.
