Bug Description

I am using http://ports.ubuntu.com/dists/oneiric/main/installer-armel/current/images/omap4/netboot/ to install encrypted guided LVM over the serial port. It installs but the installed bootloader does not have "console=ttyO2,115200", causing the passphrase prompt to not appear on reboot. This means that I cannot enter the passphrase so the system is not bootable.

Workaround: edit the SD card FAT partition as follows:

 1. dd bs=1 skip=72 if=boot.scr of=boot.script
 2. Edit boot.script and add console=ttyO2,115200
 3. Run "mkimage -A arm -O linux -T script -C none -d boot.script boot.scr" (from the u-boot-tools package)

Changed to flash-kernel-installer as it is currently hardcoded to generate the boot.script during installation regardless of cmdline settings.

If this is still relevant, I'm not sure flash-kernel is the right place for it anymore:

The flash-kernel-installer package isn't produced (as we don't produce udebs anymore), and generally speaking, flash-kernel has little to do with whatever appears on the boot partition in images. For instance, in the case of the pi images, that's down to the gadget snap (although ideally, the gadget snap would be calling something in flash-kernel to produce that output, but that's not the case currently).
