Title:
  Serial console not enabled for passphrase prompt when using LUKS

Status in “debian-installer” package in Ubuntu:
  Confirmed

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)
