Thanks for the great suggestions - they all make perfect sense. I did see the "journal present" flag, BTW, but figured that it might be safer not to change existing behavior - e.g. when someone accidentally says ext4 instead of ext2 when mounting an ext2 volume, right now they get an error. If folks are OK with this changing to a successful mount, I'm happy - less code/work is good ;-). I'll rework my patch and send out an update when it's ready. Thanks again!
