  - It has been clarified that the ``DIB_BOOTLOADER_DEFAULT_CMDLINE``
    variable appends its values to grubs
    ``GRUB_CMDLINE_LINUX_DEFAULT``, which is used during all normal
    boots but not rescue boots; as opposed to applying to
    ``GRUB_CMDLINE_LINUX``
Only append DIB_BOOTLOADER_DEFAULT_CMDLINE to default grub entry The grub.cfg has two variables [1] GRUB_CMDLINE_LINUX : used on all boots GRUB_CMDLINE_LINUX_DEFAULT : additionally used on all "normal" boots The problem with I2298675dda1f699c572b3423e7274bc8bd7c1c9d is that it appened the values in DIB_BOOTLOADER_DEFAULT_CMDLINE to both of these, resulting in duplicated arguments. I don't think we considered that GRUB_CMDLINE_LINUX_DEFAULT actually already appends to the GRUB_CMDLINE_LINUX values. Make DIB_BOOTLOADER_DEFAULT_CMDLINE only append itself to GRUB_CMDLINE_LINUX_DEFAULT. That seems to line up sensibly with the name of the variable. Documentation is enhanced around this, and a releasenote added.
