Bug#740504: cdimage.debian.org: Released ISO images have invalid GPT tables
Package: cdimage.debian.org
Severity: important
Dear Maintainer,
The GPT checksum of debian-7.4.0-amd64-netinst.iso (and other
wheezy and testing images) is incorrect due to a bug in the Xorriso build
tool used on the build system (confirmed by author of build tool). Reported on
mailing list but no response received: https://www.mail-archive.com/debian-cd@lists.debian.org/msg21403.html
I am not sure what the impact of this is (hypothetically, some EFI
systems could refuse to boot the ISO). It does mean that it is not
possible to add extra partitions to the image (which the documentation
states can be done for firmware files).
Thomas Schmitt (author of xorriso) confirmed that: "The problem
described there affects versions 1.2.6 and 1.2.8.
debian-7.3.0-amd64-netinst.iso indeed bears as preparer id
"XORRISO-1.2.6 2013.01.08.103001, LIBISOBURN-1.2.6, LIBISOFS-1.2.6,
LIBBURN-1.2.6"
It _should_ be fixed in xorriso-1.3.2 as in Debian testing
and in the current upstream release 1.3.4."
