[rdo-list] tripleo centos7 images missing linux-firmware package

Hi, I've noticed that tripleo built/CI images do not have linux-firmware package installed since they are based on the Centos 7 generic cloud image. This causes a lot of pain with the baremetal deployments that depend on the firmware to be present (in my case, bnx2 firmware is missing which causes introspection and overcloud deployment to fail, because PXE-booted images lose all network connectivity the moment networking is initialized from the image with messages like "bnx2: Can't load firmware file "bnx2/bnx2-rv2p-09ax-6.0.17.fw". Is there a good overview of the typical decision tree on where to open a bug, for which component, etc? Thanks, Ilja
