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.
- removed added-cow-option-to-bind.patch as now in upstream
* Show more information during `wwctl container <shell|exec>`
about when and if the container image will be rebuilt.
* Command-line completion for `wwctl overlay <edit|delete|chmod|chown>`.
* Display an error during boot if no container is defined.
* `wwctl container list --kernel` shows the kernel detected for
each container.
* `wwctl container list --size` shows the uncompressed size of
each container. `--compressed` shows the compressed size, and
`--chroot` shows the size of the container source on the server.
* Add a logrotate config for `warewulfd.log`.
