We just broke lock for maintenance, and TJ caught the guardian to hold it in READY just after it had completed DOWN and PREP_FOR_LOCKING.  Before anything else changed, I did a quick survey of all the SUS and ISC SDFs and accepted all of the diffs that seemed appropriate.  Since some seismic state things had been changed with the seismic guardian, I did not accept any diffs for SEI.  But, other than SEI everything is pretty well reconciled.  I hope that this will help in case we get some kind of power outage or accidental computer reboots, or in a case like this weekend where we got stuck due to some subtle filter switches that were off.
