Hi Richard,

I am sorry not to say it clearly,

1) We have been asked many times on how to install all the PACKAGES
    of a recipe, we can only list them one by one in the RDPENDS (or
    IMAGE_INSTALL and so on) currently, especially like dynamic generated
    packages (perl-modules, kernel-modules) which depends on many other
    packages, it is not easy to remember these package names for customer.
    It is helpful for user who does not take care the details that how many
    packages generated in a recipe, just want to directly install all of 
them.

2) Providing a mechanism to install all the PACKAGES of a recipe is helpful
    to test all generated packages of a recipe could work, such as the 
defect
    of '[PATCH 3/4]' was found by installing all packages of python3.

3) The fix is based on the usage of IMAGE_INSTALL, so it doesn't affect the
    users who do not want to use this feature (We disable it by default).
