Bug#465708: grub-pc: Error in postinst

[Philipp Matthias Hahn]

Package: grub-pc
Version: 1.96+20080213-1
Followup-For: Bug #465708

I upgrades my system from grub to grub-pc some time ago. After the
upgrade I cleaned up /boot/grub/ and removed all old grub files,
especially /boot/grub/menu.lst
Now upgrading grub-pc fails because of the following:

/var/lib/dpkg/info/grub-pc.config:3
	if test -e /boot/grub/menu.lst ; then
	  ...
	  db_get grub-pc/linux_cmdline
	  if [ "$RET" = "fillme" ] ; then
	  ...
	    db_set grub-pc/linux_cmdline "${kopt}" || true
	    ...
	    db_input ${priority} grub-pc/linux_cmdline || true
	  fi
	  ...
	fi

/var/lib/dpkg/info/grub-pc.templates:41
	Template: grub-pc/linux_cmdline
	Type: string
	Default: fillme

/var/lib/dpkg/info/grub-pc.postinst:15
    db_get grub-pc/linux_cmdline
    if [ "$RET" == "fillme" ] ; then
      # wtf?!
      echo "Internal error in grub-pc package.  Please file a bug report." >&2
      exit 1

Since I no longer have /boot/grub/menu.lst, the part from
"grub-pc.config" never triggers and "grub-pc/linux_cmdline" keeps it
default "fillme" from "grub-pc.template", causing "grub-pc.postinst" to
fail miserably.
