Comment(by dsd):

 IRC conversation summary:

  * zhashfs outputs .zsp file along with .zd
  * zhashfs outputs buggy .zsp file (points to wrong filename - easy to
 fix)
  * .zsp file needs to be signed into fs.zip as follows:

 {{{
 echo "data: $(cat foo.zsp)" > data.img
 $LIBEXEC/sig01 sha256 $signingkey data.img >data.sig
 }}}

 then data.img and data.sig can be zipped up into fs.zip

 then 4-gamekey reflash will cause fs.zip to be opened, signature verified,
 and the .zd filename looked up inside the .zsp
