I have seen, with my own eyes, that "jigdo-lite" gave error in the
checksum, at the end of construction of the ISO image, just as in the test
with "md5sum".
No other errors I have seen.
All files of the jigdo list are in ISO image, so write "jigdo-lite" at the
end of making the image.
I use the previous weekly ISO images, mounted on file system, for the scan
folder of jigdo-lite. I have many years I do so without problems.
