I imagine all the advantages that come with namespaces in a more advanced OS like plan 9

  How many large companies are using plan 9 in production though?

    To a first approximation... zero. That is to say, I don't know any (and I've looked a bit) and the realities of the limited hardware support make it difficult to imagine. I don't know of anybody using Inferno either, but I'm less familiar with it. I'd also dispute the suggestion that Plan9 is more advanced than Linux. It's different and Plan9 definitely does some interesting things, but that doesn't automatically make it more advanced. Ignoring that "advanced" is hard to quantify, I'd more that Plan9 is simply based on different concepts. It's like comparing Windows and Linux, albeit maybe not quite so extreme as Plan9 and Linux have more in common and Plan9 is simply not as heavily developed as either OS.

    Coraid used to build and sell systems based on Plan9, but I believe they don't exist anymore, though I don't mean to imply Plan9 was at fault, quite the contrary.

    not only is this a pretty stupid measuring stick, this non sequitur application of it comes off as needlessly defensive

  Don't think this has anything to do with anything plan9 can do that Linux can't already. The barriers to enabling the magic plan9 has are more along the lines of making it feasible for unprivileged users to mount and create namespaces themselves, which is complicated (afaik) largely by the way privilege escalation happens in unix systems. This just looks like it prevents some information from leaking out about the host system from inside a cgroup by inspecting the /proc/PID/cgroup file.
