Would the soft updates feature help any with : preventing corruption due to reboots? I don't think it would. However, I don't think that we can enable soft updates in our product w/o sending money to Kirk. And even if we didn't need to, the thing is RO for 99.9999% of the time so it wouldn't be worth it to include in our kernels in these embedded things.
