Hello,

I found debian provide several variants of iso images, including CD,
DVD, Blu-Ray, etc. However, an important variant of iso image, DVD-DL
image, is not officially released. DVD-DL (8.5G, Dual Layer DVD) nearly
doubles the capacity compared to ordinary DVD (4.7G). As software become
bigger and bigger, I think it is beneficial to release offical DVD-DL
images.

To my knowledge, most optical disc drives in PC and servers are DVD
drives, which are compatible with DVD-DL discs. And I rarely seen a
computer with Blu-Ray drives. So releasing DVD-DL images can benefit
these users directly. (Gentoo already releases their Live ISO image in
DVD-DL, and Microsoft also release Windows in DVD-DL)


Best Regards,
