README.md

05core

This overlay matches fedora-coreos-base.yaml; core Ignition+ostree bits.

08nouveau

Blacklist the nouveau driver because it causes issues with some NVidia GPUs in EC2, and we don't have a use case for FCOS with nouveau.

"Cannot boot an p3.2xlarge instance with RHCOS (g3.4xlarge is working)" https://bugzilla.redhat.com/show_bug.cgi?id=1700056

09misc

Warning about /etc/sysconfig.

14NetworkManager-plugins

Disables the Red Hat Linux legacy ifcfg format.

15fcos

Things that are more closely "Fedora CoreOS":

  • disable password logins by default over SSH
  • enable SSH keys written by Ignition and Afterburn
  • branding (MOTD)
  • enable services by default (fedora-coreos-pinger)
  • display warnings on the console if no ignition config was provided or no ssh key found.

20platform-chrony

Add static chrony configuration for NTP servers provided on platforms such as azure, aws, gcp. The chrony config for these NTP servers should override other chrony configuration (e.g. DHCP-provided) configuration.
