Title:
  grub-install --boot-directory should sanity-check for existence of
  directory

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  When running grub-install with the --boot-directory flag, grub-install
  does not check to see if the given directory exists, and passes it to
  grub-probe, which then gives a cryptic, misleading (some would say
  false and inaccurate) error message, and fails.  An improved approach
  would be something like the following in /usr/lib/grub/i386-pc/grub-
  install:

  if [ ! -d "${bootdir}" ]; then
          echo >&2 "Boot directory ${bootdir} not found."
          exit 1
  fi

  Here is the current behavior of grub-install if --boot-directory does not exist:
  $> grub-install --boot-directory /media/does-not-exist/boot /dev/sdd
  /usr/sbin/grub-probe: error: no such disk.
  Auto-detection of a filesystem of /dev/mapper/volgroup0-root failed.
  Try with --recheck.
  If the problem persists please report this together with the output of "/usr/sbin/grub-probe --device-map="/media/slitaz-th_/boot/grub/device.map" --target=fs -v /media/slitaz-th_/boot/grub" to <bug-grub at gnu.org>
