It's the way kernel.org does the updates. I upload a .xz file and a
signed gpg file of the uncompressed image. kernel.org creates the gz
file from the uncompressed version. As I upload it twice, kernel.org
does two gzips of the uncompressed file. I'm guessing that there's a
timestamp that gets used as well, making both gzipped files different,
even though what they contain are the same.

I may need to change my workflow to simply delete the file in the
current directory than to move it. Although, I had better make sure
that there's a copy in the older directory first. Maybe I'll change my
tool to download the older and current versions, uncompress them, make
sure they are the same, and if they are, remove the current version,
else, move the current version on the older one.
