The essence of /run/ had better not include that it be a
directory on the root filesystem, because the current proposal
is that it be possible for /run/ to be a RAM-based filesystem
on systems with read-only root media.

I balk at this. IMHO we should call the new directory '/run/'
if and only if we are going to use it for the same purposes
for which we use /var/run/. If the new directory is to be a
whole parallel local var hierarchy then we should call it
something like '/lvar/'. However, I don't think we need a
whole parallel local var.

/var/state/ is deprecated.
Files stored in the proposed new directory will be lost on reboot,
so it is not suited to be a "lib" directory.

/var/ contains thirteen subdirectories on my system. For which
of these is a guaranteed-to-be-local variant needed? So far,
a case has been made only for "run".
With thanks for your /run/ patches...
