So, there are two reasons why it might not work:

1) If you're using core-image-minimal, it will never be included using 
DISTRO_EXTRA_RDEPENDS (nor MACHINE_EXTRA_RDEPENDS, for that matter). This is 
because core-image-minimal does not include task-base - only the minimum 
required to get a working system.

2) Otherwise, if task-base has already been built and will be included (which 
it will be for any image that inherits from core-image and does not override 
IMAGE_INSTALL, e.g. core-image-sato) but you aren't using OEBasicHash 
(defaults to enabled for latest Poky, but not for OE-Core's default policy) 
then changing DISTRO_EXTRA_RDEPENDS after the fact won't do anything unless 
you force task-base to rebuild.

Cheers,
Paul
