Release 2023_029 (2023-11-13)

Impact

  • [NixOS 23.05] VMs will reboot after the update to activate the changed kernel.

NixOS 23.05 platform

  • Move back to Linux 5.15. We experienced multiple VM crashes and slowdowns due to a known but unsolved kernel memory management bug with the 6.1 kernel branch (PL-131574).

  • fc-maintenance commands for viewing requests (show and list) and monitoring/telemetry (check and metrics) can now be used without sudo by all users (PL-131813).

  • fc-maintenance show <request ID prefix> now has improved output and also works for archived maintenance requests. Active requests are preferred when there are multiple matches for the given request ID prefix (PL-131813).

  • Command output generated during execution of an update activity is now logged to separate files in /var/log/fc-agent, like for fc-manage calls (PL-131813).

  • Unhandled errors in fc-manage and fc-maintenance are now logged properly to the system journal and can be viewed with journalctl SYSLOG_IDENTIFIER=fc-agent (PL-131813).
