*force_output_file=*"__{yes|no}__"::
If set to _yes_, require to specify a file path for the generated initramfs
image, disabling automatic guessing of the location (default=no).
In some complex scenarios, distribution owners may want to disable the logic
for guessing the location of the output file, to prevent users from calling
