Hi,

How much padding was applied relative to the image ?
Just up to the next full 32 KiB ?


32 KiB alignment is a technical necessity with DVD. With BD it is 64 KiB.
jigdo-dvd/debian-6.0.0-amd64-DVD-1.jigdo tells me that the image
size is 4662140928 = 142277.25 * 32 * 1024.

Shall we strive for aligning the image size for DVD and BD ?
Is there a howto for vendors of Debian media ?
Is Debian in contact with vendors whom to ask for advise resp.
a description of their production process ?

I am upstream of program xorriso which produced the images
for i386 and amd64. With clear instructions i would be able
to provide an option for proper alignment.
(If the vendors do not add custom padding on their own.)


Have a nice day :)
