Ensure that smart can support the hint flags on dependencies between RPM packages that indicates that the relationship is a recommendation (RRECOMMENDS as opposed to RDEPENDS).
Implementation now merged to master: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=69b9c6bd0c6f9c9884fa2d92b4062037457d06ad
This is not working as intended: 1) Adding "gzip" to RRECOMMENDS_${PN} meta/recipes-core/packagegroups/packagegroup-core-boot.bb adds gzip to a core-image-minimal but adding "gzippp" will result in an error: ERROR: Nothing RPROVIDES 'gzippp' (but /home/cornel/SSD/poky/meta/recipes-core/packagegroups/packagegroup-core-boot.bb RDEPENDS on or otherwise requires it) If I am correct, this should generate a warning, not an error. 2) Setting RDEPENDS_udev += " gzip" in local.conf adds gzip to a core-image-minimal but setting RRECOMMENDS_udev += " gzip" does not work. Tested in master: b07759a20221de575da98d221feb9ea9295f7e6f
No, invalid package names as RRECOMMENDS are not allowed - there has to be something that RPROVIDES the recommend value even if it doesn't actually end up being satisfied at runtime; this has always been the case and has nothing to do with Smart. Also, I don't think you should expect to be able to meaningfully set R* variables from local.conf. Please do your testing within the recipe itself.
Considering the error is not smart related and that RRECOMMENDS should not be used from local.conf, this bug is verified. I will investigate and open a new bug for the error if it's needed. Verified in master:8d6e55bf2192524bda84138b5356a2791adbbe61
