Systemd v262 RC2 Drops With Zero-Downtime Kernel Updates and Varlink IPC Expansion
Systemd v262 RC2 landed on September 8 with first-class support for Linux kernel Live Update Orchestration, allowing service file descriptors to persist straight through kexec reboots without dropping connections. The candidate also cements Varlink as the primary IPC mechanism across nearly every component, while introducing systemd-imdsd for local cloud metadata access and a lightweight new OS installer. Security gets a major boost with systemd-vmspawn supporting both AMD SEV-SNP and Intel TDX, plus a complete overhaul of the TPM subsystem for measured boot and credential sealing. The final v262 release tracks for late September, though the rate-limit clock switch to CLOCK_BOOTTIME means maintainers should test suspend/resume behavior before deploying to production.
Systemd v262 RC2 Drops With Zero-Downtime Kernel Updates and Varlink IPC Expansion
Systemd v262 RC2 was released on September 8, featuring support for Linux kernel Live Update Orchestration, which allows for zero-downtime kernel updates during kexec reboots without losing service connections. The update also emphasizes Varlink as the primary IPC mechanism across systemd components and introduces systemd-imdsd for accessing local cloud metadata, along with enhanced security features for confidential computing. Additionally, the release includes a new minimal OS installer and various practical improvements, but also notable changes such as the switch to CLOCK_BOOTTIME for rate limits, which may affect service behavior. Distribution maintainers are encouraged to test these changes before the final release, expected in late September, as they could impact production environments
