Bug#785069: jessie live-installer can't install grub when booted via usb drive without internet

[Fernando Toledo <ftoledo@docksud.com.ar>]

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.

Saludos!
