Not much change this week but there is the start of exciting work to integrate support for the CEPH storage system. Here are the details of all the notable changes…

apt

The LCFG apt component has been tweaked slightly to always display an informational message when a reboot has been requested by a package. Previously this message was only displayed when there was a new reboot request.

Kernel

The INF_TEST kernel series has been updated on Noble to 6.8.0-84 and on Jammy to 5.15.0-156

The RESERVE_LOCAL_PORT macro may be used to reserve local ports to protect them from being used for any automatic port assignments. This had a bug which meant whitespace was added to the value passed to sysctl which was not legal syntax.

CEPH

Work is ongoing to merge support for the CEPH storage platform into the ed-level headers, these are based on existing configuration which is stored in external repositories.

New LCFG headers have been added – ed/options/ceph/client.h and ed/options/ceph/server.h. These are a work-in-progress, if you want to try them you need to define the CEPH_DEV macro before the inclusion of the header file.

There are also 2 new software options – LCFG_OPTIONS_CEPHADM which installs the cephadm package and LCFG_OPTIONS_CEPH_CLIENT which installs ceph-common and ceph-fuse packages. Note that they install the versions provided in the Ubuntu distribution, not the latest upstream release.

Software

There are new software package options for the following:

• LCFG_OPTIONS_PODMAN – tool to manage containers and pods
• LCFG_OPTIONS_IPTABLES – admin tools for firewalls
• LCFG_OPTIONS_QEMU_SPICE – spice display modules for QEMU

Note that iptables is included in the default base for Ubuntu platforms, the new option is just provided to simplify the dependencies of some other options.

Prior to Noble, the spice display modules were included as standard, they are now in a separate package.
