mount --bind /tmp/root.x86_64 /tmp/root.x86_64

is copied from Install_from_existing_Linux#Method_A:_Using_the_bootstrap_image_(recommended).
Why would one want to bind mount a directory over itself?
I suspect the benefits are the side effects, perhaps somethings to do with namespaces. In any case, can you elaborate?

Bizarrely, this has just been covered here: https://bbs.archlinux.org/viewtopic.php?id=242143

I thank WorMzy for pointing out that other thread.
I have tried to continue this thread at that other thread. That thread partially, or perhaps fully, answers my question. WorMzy considered my attempt as hijacking, and closed it. I think he is wrong. I think wondering about the benefits of bind mounting a directory over itself is an interesting question, and to the point in that other thread too.
If someone can explain the advantages, and disadvantageous, of such a bind mount, please do so.
