More than one device on a host

[Nathan Schmidt]

We've always had to:

mkdir /var/mogdata/dev1

and give it appropriate ownership for the mogstored process. You  
probably need to add the dev2 (or whatever devid) path explicitly.  
After that the mogstored should properly notice that it's there and  
writable.
