This week is mostly small changes for Informatics systems. Here are the details of the notable changes…

nvidia

Support for the latest 575 development series has been added. Support for older series – 535, 550, 565 – has been removed. The default series remains on the 570 production release.

The LCFG header will now also ensure that the binutils package is always included, that satisfies a dependency for the linux-objects-nvidia packages.

Kernel

The INF_TEST kernel for Jammy has been updated to 5.15.0-144 and for Noble to 6.8.0-64

runner

A couple of weeks ago the update for the LCFG runner component was deferred due to a bug in the code, this time it will hopefully behave correctly. The code has been refactored to improve the error handling and generally better maintainability.

rsyslog

DICE systems following the develop release now use a different – RSYSLOG_FileFormat – template to generate syslog records. This format generates an ISO-8601 timestamp (e.g. 2025-07-24T14:55:01.008840+01:00). This has the potential to break log parsing scripts so we will be trying it in our develop release for a few weeks.

openldap

On DICE Jammy and Noble systems the openldap TLS_CACERTDIR option is now set to /etc/ssl/certs

nut UPS monitoring

The LCFG nut2 component has gained support for sending notifications when interesting events occur. This is currently fairly simple and just provides a script for sending notifications via email but could be adapted to other mechanisms (e.g. MS Teams). When the new notify resource is specified the NOTIFYCMD option will be enabled for upsmon.conf, not that you then also need to add EXEC to the list of flags for the events of interest.

Remote access to removable media

When logged into a local session, that user has permission to mount removable media. However, when logged in remotely, such as with rdp or ssh, no permissions are granted by default. Moreover, udisks2 identifies that the user is connected to a different ‘seat’ and uses different action names. For DICE, there is a new header – dice/options/authz/allow-remote-media-mount.h which can be used allow a user to access removable media remotely, this defaults to allowing access to the allocated user for a system.

dsu

DICE Dell servers will no longer send monthly dsu (Dell System Update) reports by email. The same information is provided via the server checks page which is updated more frequently.
