Changes nothing as it isn't used due to not being available early
during boot _now_.

Not on all kernels in Debian (or at least not with sarge mount) and it
adds an ugly clutch with a race condition. Any attempt to use /var/run
after it got moved away and before it got moved back screws up. And
don't forget that mount can take a long time for journal recovery or
waiting for an nfs server.
Havin just plain /run avoids that completly.
