If everything is to end up in /usr, then I'd argue that this makes /usr
superfluous. If merging is to be done, then IMO things should be moved out
of /usr, not moved in.
well no
the point is to have a single top-level directory for a single purpose.
so distribution provided files will go to /usr, local-system
configuration in /etc, /run is for runtime state, /var is the
local-system state (the non-ephemeral state).
Let me paste this here:
»
The merged directory /usr, containing almost the entire vendor-supplied
operating system resources, offers us a number of new features regarding
OS snapshotting and options for enterprise environments for network
sharing or running multiple guests on one host. Most of this is much
harder to accomplish, or even impossible, with the current arbitrary
split of tools across multiple directories.
With all vendor-supplied OS resources in a single directory /usr they
may be shared atomically, snapshots of them become atomic, and the file
system may be made read-only as a single unit.

Well, /opt would have to go soon, too
