- Updated `wwctl upgrade` to handle updates - Maintained `.Container` and `.ContainerName` in tstruct - Added `ContainerName()` methods to node and profile objects - Added `--container`, `-C` aliases to wwctl commands (`<node|profile> <add|set>`) - Added `wwctl container` alias - Added support for `container_exit.sh` if `image_exit.sh` is not found Signed-off-by: Jonathon Anderson <janderson@ciq.com>

SELinux and IPMI write not working when using two-stage boot
|
|
============================================================
|
|
|
|
The dracut implementation of two-stage boot in versions of Warewulf prior to v4.6.0 bypasses the
|
|
``wwinit`` process by default, invoking the image's init system directly. While cluster nodes will
|
|
often still boot mostly successfully this way, features implemented by wwinit will not complete. In
|
|
particular, SELinux relabeling and IPMI write are not executed.
|
|
|
|
To ensure that dracut runs the full ``wwinit`` process, pass ``init=/init`` or
|
|
``init=/warewulf/wwinit`` on the kernel command line.
|
|
|
|
.. code-block:: bash
|
|
|
|
# wwctl profile set default --kernelargs="init=/init"

Images are read-only
|
|
====================
|
|
|
|
Warewulf v4.5 uses the permissions on an image's ``rootfs/`` to determine a "read-only" state of
|
|
the image: if the root directory of the image is ``u-w``, it will be mounted read-only
|
|
during ``wwctl image <exec|shell``, preventing interactive changes to the image.
|
|
|
|
In the past, the root directory was ``u+w``, but Enterprise Linux 9.5 (including Red Hat, Rocky, _et
|
|
al._) includes an update to the ``filesystem`` package that marks the root directory ``u-w``. This
|
|
causes Warewulf images to be "read only" by default.
|
|
|
|
To mark a Warewulf image as writeable, use `chmod u+w`.
|
|
|
|
.. code-block:: bash
|
|
|
|
# chmod u+w $(wwctl image show rockylinux-9.5)
|
|
|
|
This behavior is changed in v4.6 to use an explicit ``readonly`` file stored outside of ``rootfs/``.
