[Bug 1077622] [NEW] root= not set to UUID

[Bernd Schubert]

Public bug reported:

While creating my own custom usb boot stick grub does not properly set the root device to the UUID, but insits on sdi2. Of course, on booting from this stick sdi2 is not found and booting fails.
Reason is this part of 10_linux

  initramfs=
  if test -n "${config}" ; then
      initramfs=`grep CONFIG_INITRAMFS_SOURCE= "${config}" | cut -f2 -d= | tr -d \"`
  fi

  if test -n "${initrd}" ; then
    gettext_printf "Found initrd image: %s\n" "${dirname}/${initrd}" >&2
  elif test -z "${initramfs}" ; then
    # "UUID=" and "ZFS=" magic is parsed by initrd or initramfs.  Since there's
    # no initrd or builtin initramfs, it can't work here.
    linux_root_device_thisversion=${GRUB_DEVICE}
  fi


Removing the  linux_root_device_thisversion= overrride there properly set it to the UUID .
