There's a way to specify add_options instead of options parameter in the menuentry stanza. I have two questions about the two parameters since there's no real answer in the rEFInd manual that would clarify this.

  • Can add_options and options be mixed? Will the two following be concatenated into a longer one?
options  "..."
add_options "..."
  • Can I use multiple add_options? For instance:
add_options "..."
add_options "..."
add_options "..."

I'm asking because this would ease kernel options management -- you would need just to add # at the beginning of the line in order to comment the unneeded parameters instead of deleting them, etc.
