The first release candidate of systemd 261 is out today and it includes yet more features for this Linux init system and service manager.<\/p>\n

Systemd 261 brings new features including systemd-sysinstall as a Linux OS installer of sorts for modern environments, the Instance Metadata Service “IMDS” for expanded systemd functionality on cloud VMs, a new storagectl command, and many other additions and improvements to existing features.<\/p>\n

Some of the release highlights of systemd 261-rc1 include:<\/p>\n

– A new subsystem with systemd 261 is the Instance Metadata Service “IMDS”. This includes the new systemd-imdsd<\/strong> that makes IMDS services accessible to local programs. There is also a hardware database for recognizing established public clouds via SMBIOS information such as for Amazon EC2, Microsoft Azure, Google COmpute Engine, Oracle Cloud, Tencent Cloud, Hetzner, and others. This makes for a nice unified way of accessing virtual machine metadata from systemd.\n<\/p>\n

– Systemd 261 is also introducing storagectl<\/strong> as a new command-line tool and Varlink interface for exposing storage resources in a unified manner for use as managed user storage.\n<\/p>\n

– There is also now systemd-sysinstall<\/strong> that provides a simple, modern textual installer for an OS. This wraps around systemd’s partitioning capabilities, credential management, and other system management functionality while copying the OS from a temporary boot medium like a USB drive.

\"systemd-sysinstall\"\/<\/p>\n

– A new service systemd-tpm2-swtpm.service<\/strong> for running the IBM Software TPM “swtpm” for an automatic fallback on systems that lack a pysical TPM but where TPM functionality should be made available.<\/p>\n

– A new tmpfiles.d\/root.conf<\/strong> for ensuring that root directory permissions get set to 0555.\n<\/p>\n

– PID1 now supports the Linux kernel’s Live Update Orchestrator “LUO” and Kernel Handover “KHO” capabilities.\n<\/p>\n

– User session managers now support persisting user units’ FD Stores\n<\/p>\n

– A new unit setting of CPUSetPartition=<\/strong> allows for configuring the CPU set cgroup partition…<\/p>\n
