Comment (by jow):
Okay. So for now it looks like the xattr which tracks the completion state
gets corrupted in jffs2's "/" leading the system to believe that the
overlay needs to cleared and rebuilt again on next boot.
To gain additional clues it would make sense to add a little bit more
tracking around the xattr handling, like that:
