Yeah, after I saw that bug it does seem to be solely a data flushing
issue.  I was trying the testcase and looking at what is on-disk in the
original image, what's on-disk after the unmount, and what is seen in
the chroot, for the file in question.... 3 different answers.

(and oddly enough dropping caches doesn't show it; you have to
unmount/remount)
