v4.6.5 Release Notes
====================
v4.6.5 is a regularly-scheduled minor release in the v4.6.x series.
Significant changes are described below. Additional changes are listed in the
`CHANGELOG`_.
.. _CHANGELOG: https://github.com/warewulf/warewulf/blob/main/CHANGELOG.md
wwctl overlay info
==================
A new ``wwctl overlay info`` command lists variables used by an overlay
template, including the ``wwctl <node|profile> set`` argument used to set that
variable.
.. code-block: console
# wwctl overlay info ifcfg /etc/sysconfig/network-scripts/ifcfg.ww
VARIABLE OPTION TYPE HELP
-------- ------ ---- ----
$netdev.Device --netdev string Set the device for given network
$netdev.Gateway --gateway IP Set the node's IPv4 network device gateway
$netdev.Hwaddr --hwaddr MAC Set the device's HW address for given network
$netdev.Ipaddr --ipaddr IP IPv4 address in given network
$netdev.Ipaddr6 --ipaddr6 IP IPv6 address in given network
$netdev.MTU --mtu uint Set the mtu
$netdev.Netmask --netmask IP Set the networks netmask
$netdev.OnBoot --onboot wwtype.WWbool Enable/disable network device (true/false)
$netdev.Tags map[string]string
$netdev.Tags.DNSSEARCH string
$netdev.Tags.master string
$netdev.Type --type string Set device type of given network
.NetDevs map[string]*node.NetDev
Other variables and the overlay itself can also be documented explicitly within a template.
.. code-block:: text
{{/* wwdoc: Configures chronyd to synchronize time with a specific time server. */}}
{{/* .Tags.ntp_server: the NTP server to synchonize with */}}
wwctl image import --update
===========================
The ``wwctl image import`` come has included an ``--update`` option since
v4.6.0, but it has not been functional. The option now imports an image
on-top-of an existing image and is meant to be used to update an existing image
with new files from an updated upstream or external image (e.g., by importing a
new version of an image from an OCI registry).
wwclient
========
One of the last real impediments to multi-architecture support in Warewulf has
been the wwclient daemon which, though distributed to cluster nodes, has been
built only for the architecture of the Warewulf server. Now, new
``wwclient.aarch64`` and ``wwclient.x86_64`` overlays provide
architecture-specific builds of wwclient for aarch64 and x86_64 nodes,
respectively.
wwclient has also been enhanced with IPv6 support, and now properly handles
recently-used addresses when restarting.
Network management
==================
A number of network management improvements have been made. Most deal with
improving IPv6 support. The ``debian.interfaces`` overlay has been renamed to
``ifupdown`` to better reflect its support for both Debian, Ubuntu, and Alpine
systems. The ``netplan`` and ``NetworkManager`` overlay have improved support
for bonded interfaces; and a new ``systemd-networkd`` overlay adds support for
the systemd networking daemon.
Packaging
=========
The openEuler 24.03 RPM package now uses dnsmasq by default.
Development
===========
Work has resumed on support for using Vagrant to initialize a basic testing /
development environment with libvirt.
warewulf-dracut
===============
A bug between ``warewulf-dracut`` and the ``ignition`` overlay previously caused
non-root filesystems from mounting when provisioning the image to disk. A fix in
``warewulf-dracut`` prevents ignition from running twice, allowing all file
systems to mount properly. The ``wwinit`` dracut module also no longer runs the
wwinit module if root is not set to `root=wwclient*`.
These fixes require installing the updated ``warewulf-dracut`` package in the
node image.
Other fixes
===========
- Enhanced `wwctl configure tftp` to manage the SELinux context of TFTP directory. #1997
- Enhanced overlay templates to support absolute paths with `{{ file }}`. #2055
- Fix ImageDelete API not returning error when checking if image is used by nodes/profiles. #1705
- Fix filesystem overwrite/force behavior in `mkfs` overlay. #2028
- Write `$tftpdir/warewulf/grub.cfg` to `tftproot` as configured in `warewulf.conf`. #2055
- Automatically create a GPT label when `sfdisk` overlay wipes disks. #2025
