As I understand it the rebuild only removes RedHat copyrighted artifacts like their name and logo. This is also why the release notes refer to 'upstream' rather than RedHat by name (not that I studied it in depth recently) The only 'poison' here is copyright, which CentOS avoids by removing these artifacts.That said I am not a lawyer. ----- Original Message ----- From: "CentOS mailing list" To:"CentOS mailing list" Cc: Sent:Wed, 3 Jul 2019 08:43:40 +0200 Subject:[CentOS] using RedHat binary packages? Hi folks, AFAIK CentOS uses RedHat's source RPMs for building the next CentOS release. I am not sure about the bootstrap procedure and the infra- structure packages, so lets put these corner cases aside. .... snip.. My question is: Are RedHat's binary RPMs "poisoned" somehow, making it impossible for CentOS to redistribute RedHat's *binary* packages without going to jail?
