Yeah, that's what I suspected. I figured there were probably additional things done other than init stopping running processes before the device is safely shutdown. I would assume that the current script I have is killing the applications first, and then unmounting the volume.
I'll look into SYSD some more. This was just such a tempting shortcut though, that I couldn't resist trying it to see what would happen. Oh well.
