1. An information handling system comprising:
at least one processor; and
a non-transitory memory coupled to the at least one processor;
wherein the information handling system is a node of an information handling system cluster; and
wherein the node is configured to be imaged while the node is operational within the information handling system cluster and while secure boot is enabled for the node, wherein the imaging includes installing a new version of a management system to the node, by:
enabling a serial over LAN (SOL) interface configured to provide monitoring information regarding the imaging;
a node installation service executing on the node creating a partition on a storage medium of the node;
the node installation service receiving an image bundle from a remote information handling system via a network and storing the image bundle on the partition;
the node installation service updating a boot loader configuration file for the management system;
the node installation service creating a kickstart file that indicates one or more actions to be taken with regard to the imaging of the node;
the node installation service causing the node to reboot, wherein the rebooting is configured to install the new version of the management system to the node from the image bundle based on the boot loader configuration file an the kickstart file; and
in response to completion of the installation, deactivating the SOL interface.
