In crossdev, when a package fails you have to redo all the steps of building binutils, glibc, gcc etc, even if it's only the last that failed. But if you could pass -nN to emerge, that would skip the already installed package to resume only the failed one. It'a a 2-lines patch. Reproducible: Always Steps to Reproduce: N/A Actual Results: It remerges every package, including the already-installed ones Expected Results: Remerging only the failed one, skipping the others.
no it doesnt ... the packages already built are not re-emerged
