Would there be harm is automatically updating the md5 check sums after the upcp runs? Since I could not find a specific parameter/switch on LFD to perform this operation, perhaps something like this could be added to the /scripts/postupcp file...
Obviously the other place this would need to be handled is in the post OS level updates (post yum, etc)... But perhaps adding a parameter/switch to LFD to force recalculate the md5 checksums would allow a bit of flexibility...
