RpmPM's respective install() implementation deviates somewhat from it's OpkgPM, DpkgPM counterparts. It seems that rpm applies '--skip-broken' switch to dnf command which supposedly ignores just the conflicting packages in a given set, while installing all others.

The behaviour in opkg/dpkg case however seems to be, that in case of even single conflicting package in a package set, the whole package set is silently left uninstalled. I performed a test against a reference image where the issue manifests, and compared to rpm, opkg/dpkg-based SDK images lacked over half of target packages:

$ wc -l toolchain-target-manifest-*
  317 toolchain-target-manifest-deb
  317 toolchain-target-manifest-ipk
  653 toolchain-target-manifest-rpm
