Fixing the script removes the state file before it is checked on boot, 
so I do not think it is necessary to move the state file to a volatile 
file system. I'm going to push the fix to the ifupdown package. There is 
also ifupdown-ubuntu, but I am not sure who is using that. It references 
/var/run/....
