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

[hbayindir@gmail.com]

Hello,

I've found out that debian-installer-launcher is always preseeding the live-
installer with some options. I've modified debian-installer-launcher to force-
load apt-cdrom-setup udeb, which solved the problem. I've opened a bug report 
against debian-installer-launcher, which can be seen at [0]. If that patch can 
be included in the package, problem can be solved without modifying the d-i.

Best regards,

Hakan
