+- start the ISO with qemu `bash run.sh`
+Install the system with a cloud-config file adding `fips=1` to the boot options:
 
+```yaml
+#cloud-config
+
+install:
+  # ...
+  # Set grub options
+  grub_options:
+    # additional Kernel option cmdline to apply
+    extra_cmdline: "fips=1"

+Notes:
+- The dracut patch is needed as Ubuntu has an older version of systemd
+- Most of the Dockerfile configuration are: packages being installed by ubuntu, and the framework files coming from Kairos containing FIPS-enabled packages
