Feature Status

The following table summarizes the maturity of Warewulf’s top-level features. Features are classified as follows:

• Stable – Production-ready; the interface is well-tested and unlikely to change in incompatible ways.

• Preview – Functional, but may have rough edges, limited testing, or an interface that is still evolving.

• Incomplete – Work-in-progress; key functionality or the user-facing interface is not yet complete.

Feature	Status	Notes
iPXE	Stable	Default network bootloader used for PXE booting cluster nodes.
GRUB	Preview	Alternative bootloader; useful for UEFI and Secure Boot scenarios.
Single-stage boot	Stable	Default provisioning mode; the OS image is used directly as the root filesystem.
Two-stage boot	Preview	Uses an intermediate initrd to initialize hardware before loading the final OS image. Requires Dracut-based images.
Nodes	Stable	Core node management (add, remove, configure, list).
Profiles	Stable	Abstract node profiles for sharing configuration across groups of nodes.
Overlays	Stable	Template-based file provisioning applied to OS images at boot and at runtime.
OS images	Stable	Container-based OS image import, management, and provisioning.
Read-only images	Preview	Marking an image read-only to enable future support for image subscriptions and updates.
Kernels	Stable	Kernel extraction from OS images and per-node kernel management.
Disk provisioning	Preview	Partitioning and formatting disks on cluster nodes during provisioning.
Provision-to-disk	Preview	Provisioning an OS image to disk so that the node can subsequently boot without Warewulf.
Resources	Incomplete	Generic node resources; the user-facing interface is not yet complete.
Secure Boot	Preview	UEFI Secure Boot support via signed bootloaders.
dnsmasq	Preview	Using dnsmasq as an alternative to ISC dhcpd and TFTP for DHCP and network boot services.
