The published interface applies to those scripts that can depend (directly or indirectly) on rcconf.sh. Before that point rc.conf=20 is not sourced in the script's environment so entropy_file is not defined. I'm pretty sure this change makes 'feed_dev_random "/entropy"' into 'feed_dev_random ""'. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
