In the second emerge call I omit --rebuild-if-new-rev, becasue it makes no sense with -B together. But I would like -k not to rule out --rebuild-if-new-rev, if at all possible. The use case for that is automatic nightly pre-packaging with the second emerge call, followed by the third one run manually. The point is to use --rebuild-if-new-rev, but be spared (during the day) of as much compiling time as possible, while avoiding automatic merging of anything into / in cron as some stuff needs attention right after the merge.

(In reply to comment #0) > But I would like -k not to rule out > --rebuild-if-new-rev, if at all possible. While reviewing the relevant code in /usr/lib/portage/pym/_emerge/depgraph.py, I found this code which appears related to the behavior you observe: def _needs_rebuild(self, dep_pkg): """Check whether packages that depend on dep_pkg need to be rebuilt.""" dep_root_slot = (dep_pkg.root, dep_pkg.slot_atom) if dep_pkg.built or dep_root_slot in self.orig_rebuild_list: return False As you can see, if dep_pkg.built is True then it returns False and does not rebuild the parent package. There's some related code in the _trigger_rebuild method which deals with binary packages, but the logic seems to assume that any necessary rebuilds would have been triggered in an earlier build (which would have happened if you weren't using --buildpkgonly).
Thanks for finding the key. I'll do some additional good old manual emerging before this gets to portage. I lack the portage sourcecode knowledge that's required to investigate this thing with reasonable efficiency.
