[Mark Bergsma]

I don't think this was the same bug, as it's still happening with grub-
installer 1.49ubuntu11.2 installs in Lucid.

Title:
  serial console output does not work

Status in “grub-installer” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: grub2

  After installing Ubuntu 9.10 server edition using a serial console (on
  ttyS1), Grub2 fails to use the serial console as output device, and
  instead displays the following error messages:

  error: bad unit number
  error: unknown command `terminal'
  error: unknown command `terminal'

  These are the contents of /etc/default/grub:

  # If you change this file, run 'update-grub' afterwards to update
  # /boot/grub/grub.cfg.

  GRUB_DEFAULT=0
  GRUB_HIDDEN_TIMEOUT=0
  GRUB_HIDDEN_TIMEOUT_QUIET=true
  GRUB_TIMEOUT="10"
  GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
  GRUB_CMDLINE_LINUX_DEFAULT=""
  GRUB_CMDLINE_LINUX="console=ttyS1,115200n8"

  # Uncomment to disable graphical terminal (grub-pc only)
  #GRUB_TERMINAL=console

  # The resolution used on graphical terminal
  # note that you can use only modes which your graphic card supports via VBE
  # you can see them in real GRUB with the command `vbeinfo'

  # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
  #GRUB_DISABLE_LINUX_UUID=true
