Since /var/run is a subdir of /var which might be separate file system
it is difficult mounting /var/run before /var. That means that it won't
be available in the intird.
(Yes, one can do stuff with show-through mount hierachies, that would
allow replacing /var later on, but I am not a fan of such hackery.)
Also note that by now it's somewhat standard that code that needs to be
run as part of early boot creates a subdir in /dev, such as /dev/.udev
or /dev/.systemd. Not super-pretty, but I guess it's too late to
complain about that.
Ideally the FHS would have never specified that /var/run and /var/lock
would lie beneath /var, but I guess that's too late now.
