==== Configuring kernel arguments for the Discovery ISO by using GitOps ZTP

{product-title} now supports specifying kernel arguments for the Discovery ISO in GitOps ZTP deployments. In both manual and automated GitOps ZTP deployments, the Discovery ISO is part of the {product-title} installation process on managed bare-metal hosts. You can now edit the `InfraEnv` resource to specify kernel arguments for the Discovery ISO. This is useful for cluster installations with specific environmental requirements. For example, you can define the **rd.net.timeout.carrier** kernel argument to help configure the cluster for static networking.

For more information about how to specify kernel arguments see the following documentation:

xref:../scalability_and_performance/ztp_far_edge/ztp-deploying-far-edge-sites.adoc#setting-managed-bare-metal-host-kernel-arguments_ztp-deploying-far-edge-sites[Configuring kernel arguments for the Discovery ISO by using GitOps ZTP].

xref:../scalability_and_performance/ztp_far_edge/ztp-manual-install.adoc#setting-managed-bare-metal-host-kernel-arguments_ztp-manual-install[Configuring kernel arguments for the Discovery ISO for manual installations by using GitOps ZTP].
