That seems to have worked well.
I wonder whether this means that it would be better to stop adding the
recommends automatically and tell users that need this to use
IMAGE_INSTALL_COMPLEMENTARY instead (either directly, or by teaching
license_image.bbclass to modify it based on another variable.)
Losing the recommends would also meaan I wouldn't need to add
--no-recommends to the image recipes that don't need the licence files.
Thanks for the speedy response!
Mike.
