Hi,

I don't really know where to file that; please reassign if I'm wrong.

I recently downloaded the debian-installer netboot archive at
http://debian.univ-nantes.fr/debian/dists/wheezy/main/installer-amd64/current/images/netboot/gtk/netboot.tar.gz
which is the GTK version of the netboot installer (this bug doesn't
affect the text version).

I noticed, after unpacking it and checking for the sums, hoping that
they will be the same as if I downloaded all the files individually,
that they all validate except one: the initrd.gz for this installer. (I
checked the sum of the .tar.gz itself, and it's OK).

The sums are, e.g., here:
http://debian.univ-nantes.fr/debian/dists/wheezy/main/installer-amd64/current/images/SHA256SUMS

When getting directly the initrd.gz from
http://debian.univ-nantes.fr/debian/dists/wheezy/main/installer-amd64/current/images/netboot/gtk/debian-installer/amd64/initrd.gz
I correctly get
f8971317915ed2ce8358b24ca88ea95c75ebe97a1e0a95f60c7977da368b3352
But when extracting it from the archive, I get
c2103b9533baa88814e770b493e5ba93f3043f3d73ce6e018addcd7c84b22cd4

By looking closer, the uncompressed initrd from both files is the same.
Only the date (from the gzip header) differs by a couple of seconds. And
this only happens for the GTK installer, not the text one, once again…

Furthermore, I also realized that Ubuntu is affected, too (!); the sum
for the GTK installer of Precise Pangolin has the same problem.

There must be a small packaging bug somewhere…

Done.
