The workaround of running apt-cdrom add from the installer chroot as say the comment #25 work for me:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=785069#25 I'm research if is possible to run via internal hooks of debian-installer but i do not know exactly where put the simple bash script that run "in-target apt-cdrom add" that must run before grub-installer step. If found some comment in this bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=678611#10 That mention posible paths like usr/lib/finish-install.d usr/lib/pre-pkgsel.d usr/lib/post-base-installer.d and more... Any guy that know more d-i internals can help here. I use live-build, and i think can be easy put that script on: config/includes.installer/usr/lib* and shipp it on the installer part of the final iso live image.
