Warewulf v4.5.8 simplifies the "wwinit" boot process for SELinux and configures tmpfs to spread the node image across all available NUMA nodes. It also improves the detection of kernels in the container image to more reliably detect the newest available kernel and to avoid debug / rescue kernels.

This release also includes additional bug fixes and documentation improvements.
