I added a couple of Installer Kernel Parameters, “net.ifnames=0” and “biosdevname=0”, to try and disable “consistent network device naming”. Apparently these were causing the wait. I removed them and did not experience the wait.
Unfortunately without these parameters the old network device names are not detected and configured correctly from the Installer Kernel.
After the deployment the newly installed kernel boots and does not experience any wait when these two parameters are used, regardless of whether the Installer used them or not.
