I just discovered what appears to be a bug: I added a new worker and then edited its pool (but didn't actually change any data; just wanted to make sure it was configured properly).  That new worker/pool was automatically ranked first in the list of Failover profiles even though I hadn't changed anything about the Failover order.  I had to manually edit the Failover order back to what it was before the addition of the new worker.

On an unrelated note, I would also like to know how to launch smartcoin automatically at system startup.  What lines need to be added to which files to accomplish this?  Can I stick something in /etc/init.d/rc.local (which is how I started miners before smartcoin)?
