Yes, it will. You would need to clean and rebuild task-base because unlike the 
other methods the dependency gets built into a task package.

This is one of the reasons you should not use DISTRO_EXTRA_RDEPENDS from 
local.conf - this is intended to be set from the distro configuration only. 
Please don't recommend this to be modified from local.conf - stick to 
CORE_IMAGE_EXTRA_INSTALL (or IMAGE_INSTALL_append, if you must).

Cheers,
Paul
