Note that the modification time is different, so dirvish won't hardlink
this file from the previous image, as it is NOT the same file in all
respects; if it did, then the information about the modification time
would be lost.

This is an extra note, in addition to the other points already brought
up... so don't complain that it doesn't do the hardlinking even if you
do cp -p :-)
