point a file belongs to. you specify which znodes represent a
container entry point (what you are calling a mount point). a znode

belongs to. i believe in this sense the two proposals are both the

The idea here is to make much smaller and more intuitive changes.

Also - in Linux mount you don't need to specify for each new file which mount point the file belongs to - we can exploit the tree structure to infer that instead of creating and maintaining an additional hierarchy like in the previous proposal.
