- 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. - Warewulf v4.5.7 fixes the ability to override overlay files configured in profiles with overlays configured per-node; fixes a template processing bug bug in development-time overlay rendering; and improves the preview dracut-based boot process to better support a "secure" boot process. - rmeoved added-cow-option-to-bind.patch as now in upstream OBS-URL: https://build.opensuse.org/package/show/network:cluster/warewulf4?expand=0&rev=90
