> In an image recipe you can't use RRECOMMENDS to specify a list of packages that extend the usability of the image being built.  In this type of recipe you can use PACKAGE_INSTALL_ATTEMPTONLY that has the same functionality.

and I think both can be used, from below, it tells me, they can perform 
the same function, do you try RRECOMEEDS and meet an error?

lyang001 at lyang0-9010:~/intel-xeon-core/layers/oe-core/meta/classes$ cat 
image.bbclass |grep -E "^RRECOM|^PACKAGE_INSTALL_ATTEMPTONLY"
RRECOMMENDS += "${NORMAL_FEATURE_INSTALL_OPTIONAL}"
PACKAGE_INSTALL_ATTEMPTONLY ?= "${FEATURE_INSTALL_OPTIONAL}"
