I seem to have struck a wall, mostly because I don't understand what's going on behind the curtains. Currently, I get a system that will boot up until it's supposed to mount the root file system, then it drops to emergency shell, telling me that there's no support for ext4 in my initramfs. I just copied the CentOS 7 files in the configuration, but it seems like there's more to it. Has anyone successfully installed CentOS 8 or RHEL 8 with fai, and care to share any tips and tricks? Best regards, Daniel
