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.
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.
# 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.
{{/* wwdoc: Configures chronyd to synchronize time with a specific time server. */}}
{{/* .Tags.ntp_server: the NTP server to synchronize with */}}
wwctl image import –update
The wwctl image import command 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 prevented
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
OS image.
