systemd System and Service Manager
+CHANGES WITH 246 in spe:
+
+ * The various programs included in systemd can now optionally output
+ their log messages on stderr prefixed with a timestamp, controlled by
+ the $SYSTEMD_LOG_TIME environment variable.
+
+ * A new boolean kernel command line option systemd.swap= has been
+ added, which may be used to turn off automatic activation of swap
+ devices, as listed in /etc/fstab.
+
+ * The CPUAffinity= setting in service unit files now supports a new
+ special value "numa". If used, the NUMA mask is copied into the CPU
+ affinity mask.
+
+ * The man pages for the sd-bus and sd-hwdb APIs have been completed.
+
+ * networkctl gained the new "forcerenew" command for forcing all DHCP
+ server clients to renew their lease. The interface "status" output
+ will now show numerous additional fields of information about an
+ interface. There are new "up" and "down" commands to bring specific
+ interfaces up or down.
+
+ * systemd-networkd's [IPv6Prefix] section in .network files gained a
+ new boolean setting Assign=. If enabled an address from the prefix is
+ automatically assigned to the interface.
+
+ * systemd-networkd's [Network] section gained a new setting
+ IPv6PDSubnetId= that allows explicit configuration of the preferred
+ subnet that networkd's Prefix Delegation logic assigns to an
+ interfaces.
+
+ * systemd-networkd gained support for configuring the HTB queuing
+ discipline in the [HierarchyTokenBucket] and
+ [HierarchyTokenBucketClass] sections. Similar the "pfifo" qdisc may
+ be configured in the [PFIFO] section, "GRED" in
+ [GenericRandomEarlyDetection], "SFB" in [StochasticFairBlue], "cake"
+ in [CAKE], "PIE" in [PIE], "DRR" in [DeficitRoundRobinScheduler] and
+ [DeficitRoundRobinSchedulerClass], "BFIFO" in [BFIFO],
+ "PFIFOHeadDrop" in [PFIFOHeadDrop], "PFIFOFast" in [PFIFOFast] and
+ "HHF" in [HeavyHitterFilter].
+
+ * systemd-networkd gained support for a new Termination= setting in the
+ [CAN] section for configuring the termination resistor. It also
+ gained a new ListenOnly= setting for controlling whether to only
+ listen on CAN interfaces, without interfering with traffic otherwise
+ (which is useful for debugging/monitoring CAN network
+ traffic). DataBitRate=, DataSamplePoint=, FDMode=, FDNonISO= have
+ been added to configure various CAN-FD aspects.
+
+ * .link files managed by systemd-udevd gained options RxFlowControl=,
+ TxFlowControl=, AutoNegotiationFlowControl= in the [Link] section, in
+ order to configure various flow control parameters. They also gained
+ RxMiniBufferSize= and RxJumboBufferSize= in order to configure jumbo
+ frame ring buffer sizes.
+
+ * systemd-networkd's [DHCPv6] section gained a new WithoutRA= boolean
+ setting. If enabled, DHCPv6 will be attempted right-away without
+ requiring an Router Advertisement packet suggesting it
+ first. Conversely, the [IPv6AcceptRA] gained a boolean option
+ DHCPv6Client= that may be used to turn off the DHCPv6 client even if
+ the RA packets suggest it.
+
+ * systemd-networkd's [DHCPv4] section gained a new setting UseGateway=
+ which may be used to turn off use of the gateway information provided
+ by the DHCP lease. A new FallbackLeaseLifetimeSec= setting may be
+ used to configure how to process leases that lack a lifetime option.
+
+ * systemd-networkd's [DHCPv4] and [DHCPServer] sections gained a new
+ setting SendVendorOption= allowing configuration of additional vendor
+ options to send in the DHCP requests/responses. The [DHCPv6] section
+ gained a new SendOption= setting for sending arbitrary DHCP
+ options. RequestOptions= has been added to request arbitrary options
+ from the server. UserClass= has been added to set the DHCP user class
+ field.
+
+ * systemd-networkd's [DHCPServer] section gained a new set of options
+ POP3Servers=, SMTPServers=, LPRServers= for including server
+ information about these three protocols in the DHCP lease. It also
+ gained support for including "MUD" URLs ("Manufacturer Usage
+ Description"). Support for "MUD" URLs was also added to the LLDP
+ stack, configurable in the [LLDP] section in .network files.
+
+ * systemd-resolved's DNS= configuration option now optionally accepts
+ DNS server addresses suffixed by "#" followed by a host name. If
+ used, the DNS-over-TLS certificate is validated to match the
+ specified hostname.
+
+ * The fs.suid_dumpable sysctl is set to 2 / "suidsafe". This allows
+ systemd-coredump to save core files for suid processes. When saving
+ the core file, systemd-coredump will use the effective uid and gid of
+ the process that faulted.
+
+ * "systemctl list-units" and "systemctl list-machines" no longer hide
+ their first output column with --no-legend. To hide the first column,
+ use --plain.
+
+ * The service manager gained basic support for cgroup v2 freezer. Units
+ can now be suspended or resumed either using new systemctl verbs,
+ freeze and thaw respectively, or via D-Bus.
+
+ * A new sd-path.h API has been added to libsystemd. It provides a
+ simple API for retrieving various search paths and primary
+ directories for various resources.
+
+ * The sd-bus API gained a number of convenience functions that take
+ va_list arguments rather than "...". For example, there's now
+ sd_bus_call_methodv() to match sd_bus_call_method(). Previously,
+ these were missing since the calls are convenience calls only and
+ could be put together from the more low-level functions they build
+ on.
+
+ * sd-bus vtable entries learnt a new flag SD_BUS_VTABLE_ABSOLUTE_OFFSET
+ which alters how the userdata pointer to pass to the callbacks is
+ determined. If the flag is set the offset field is converted as-is
+ into a pointer, without adding it to the object pointer the vtable is
+ associated with.
+
+ * sd-bus now exposes four new functions:
+ sd_bus_interface_name_is_valid() + sd_bus_service_name_is_valid() +
+ sd_bus_member_name_is_valid() + sd_bus_object_path_is_valid() will
+ validate strings to check if they qualify as various D-Bus concepts.
+
+ * The sd-bus API gained the SD_BUS_METHOD_WITH_ARGS(),
+ SD_BUS_METHOD_WITH_ARGS_OFFSET() and SD_BUS_SIGNAL_WITH_ARGS() macros
+ that simplify adding argument names to D-Bus methods and signals.
+
+ * systemctl gained a new "-P" switch that is a shortcut for "--value
+ --property=…".
+
+ * The expectations on user/group name syntax are now documented in
+ detail; documentation how classic home directories may be converted
+ into home directories managed by homed has been added; documentation
+ regarding integration of homed/userdb functionality in desktops has
+ been added:
+
+ https://systemd.io/USER_NAMES
+ https://systemd.io/CONVERTING_TO_HOMED
+ https://systemd.io/USERDB_AND_DESKTOPS
+
+ * systemd-run gained a new switch --slice-inherit. If specified the
+ unit it generates is placed in the same slice as the systemd-run
+ process itself.
+
+ * service unit files now accept a new setting CoredumpFilter= which
+ allows configuration of the memory sections coredumps of the
+ service's processes shall include.
+
+ * coredumpctl gained a new --file= switch, matching the same one in
+ journalctl: a specific journal file may be specified to read the
+ coredump data from.
+
+ * Various D-Bus APIs of systemd daemons now have man pages that
+ document the methods, signals and properties.
+
+ * journald.conf gained a new boolean setting Audit= that may be used to
+ control whether systemd-journald will enable audit during
+ initialization.
+
+ * A new default .network file is now shipped that matches TUN/TAP
+ devices that begin with "vt-" in their name. Such interfaces will
+ have IP routing onto the host links set up automatically. This is
+ supposed to be used by VM managers to trivially acquire a network
+ interface which is fully set up for host communication, simply by
+ carefully picking an interface name to use.
+
+ * All D-Bus services shipped in systemd now implement the generic
+ LogControl1 D-Bus API which allows clients to change log level +
+ target of the service during runtime.
+
+ * systemd-nspawn's --resolv-conf= switch gained a number of new
+ supported values. Specifically, options starting with "replace-" are
+ like those prefixed "copy-" but replace any existing resolv.conf
+ file. And options ending in "-uplink" and "-stub" can now be used to
+ propagate other flavours of resolv.conf into the container (as
+ defined by systemd-resolved).
+
+ * systemd-binfmt gained a new switch --unregister for unregistering all
+ registered entries at once. This is now invoked automatically at
+ shutdown, so that binary formats registered with the "F" flag will
+ not block clean file system unmounting.
+
+ * Unit files, tmpfiles.d/ snippets, sysusers.d/ snippets and other
+ configuration files that support specifier expansion learnt six new
+ specifiers: %a resolves to the current architecture, %o/%w/%B/%W
+ resolve to the various ID fields from /etc/os-release, %l resolves to
+ the "short" hostname of the system, i.e. the kernel configured
+ hostname, truncated at the first dot.
+
+ * systemd-notify's --pid= switch gained new values: "parent", "self",
+ "auto" for controlling which PID to send to the service manager: the
+ systemd-notify process' PID, or the one of the process invoking it.
+
+ * When sending a file descriptor (fd) to the service manager to keep
+ track of, using the sd_notify() mechanism, a new parameter FDPOLL=0
+ may be specified. If passed the service manager will refrain from
+ poll()ing on the file descriptor. Traditionally (and when the
+ parameter is not specified), the service manager will poll it for
+ POLLHUP or POLLERR events, and immediately close the fds in that
+ case.
+
+ * A new call sd_notify_barrier() has been added to the sd-daemon.h
+ API. The call will block until all previously sent sd_notify()
+ messages have been processed by the service manager. This is useful
+ to remove races caused by a process already having disappeared at the
+ time a notification message is processed by the service manager,
+ making correct attribution impossible. The systemd-notify tool will
+ now make use of this call implicitly, but this can be turned off again
+ via the new --no-block switch.
+
+ * systemd-logind's Session bus object learnt a new method call
+ SetType() for temporarily updating the session type of an already
+ allocated session. This is useful for upgrading tty sessions to
+ graphical ones once a compositor is invoked.
+
+ * .mount units gained a new ReadWriteOnly= boolean option. If set
+ it will not be attempted to mount a file system read-only if mounting
+ in read-write mode doesn't succeed. An option x-systemd.rw-only is
+ available in /etc/fstab to control the same.
+
+ * coredumps collected by systemd-coredump may now be compressed using
+ the zstd algorithm.
+
+ * journalctl's "-o cat" output mode will now show one or more journal
+ fields specified with --output-fields= instead of unconditionally
+ MESSAGE=. This is useful to retrieve a very specific set of fields
+ without any decoration.
+
+ * systemd-socket-proxy gained a new switch --exit-idle-time= for
+ configuring an exit-on-idle time.
+
+ * systemd-homed's LUKS backend gained the ability to discard empty file
+ system blocks automatically when the user logs out. This is enabled
+ by default to ensure that home directories take minimal space when
+ logged out but get full size guarantees when logged in. This may be
+ controlled with the new --luks-offline-discard= switch to homectl.
+
+ * If systemd-homed detects that /home/ is encrypted as a whole it will
+ now default to the directory or subvolume backends instead of the
+ LUKS backend, in order to avoid double encryption. The default
+ storage and file system may now be configured explicitly, too, via
+ the new /etc/systemd/homed.conf configuration file.
+
+ * when systemd-journald's log stream is broken up into multiple lines
+ because the PID of the sender changed this is indicated in the
+ generated log records via the _LINE_BREAK=pid-change field.
+
+ * systemd-networkd's .netdev files now support a new setting
+ VLANProtocol= in the [Bridge] section that allows configuration of
+ the VLAN protocol to use.
+
+ * systemd-repart's --empty= setting gained a new value "create". If
+ specified a new empty regular disk image file is created under the
+ specified name. Its size may be specified with the new --size=
+ option. The latter is also supported without the "create" mode, in
+ order to grow existing disk image files to the specified size. These
+ two new options are useful when creating or manipulating disk images
+ instead of operating on actual block devices.
+
+ * systemd-repart drop-ins now support a new UUID= setting to control
+ the UUID to assign to a newly created partition.
+
+ * StandardError= and StandardOutput= in unit files no longer support
+ the "syslog" and "syslog-console" switches. They were long removed
+ from the documentation, but will now result in warnings when used,
+ and be converted to "journal" and "journal+console" automatically.
+
+ * systemd-networkd supports a new Group= setting in the [Link] section
+ of the .network files, to control the link group.
+
+ * Two new unit file settings
+ ConditionPathIsEncrypted=/AssertPathIsEncrypted= have been
+ added. They may be used to check whether a specific file system path
+ resides on a block device that is encrypted on the block level
+ (i.e. using dm-crypt/LUKS).
+
+ * Another pair of new settings ConditionEnvironment=/AssertEnvironment=
+ has been added that may be used for simple environment checks. This
+ is particularly useful when passing in environment variables from a
+ container manager (or from PAM in case of the systemd --user
+ instance).
+
+ * The /sys/module/kernel/parameters/crash_kexec_post_notifiers file is
+ now automatically set to "Y" at boot, in order to enable pstore
+ generation for collection with systemd-pstore.
+
+ * New kernel command line options systemd.condition-needs-update= and
+ systemd.condition-first-boot= have been added, which override the
+ result of the ConditionNeedsUpdate= and ConditionFirstBoot=
+ conditions.
+
+ * A new kernel command line option systemd.clock-usec= has been added
+ that allows setting the system clock to the specified time in µs
+ since Jan 1st, 1970 early during boot. This is in particular useful
+ in order to make test cases more reliable.
+
+ * A new kernel command line option systemd.hostname= has been added
+ that allows controlling the hostname that is initialized early during
+ boot.
+
+ * The /etc/crypttab tmp option now optionally takes an argument
+ selecting the file system to use. Moreover, the default is now
+ changed from ext2 to ext4.
+
+ * There's a new /etc/crypttab option "keyfile-erase". If specified the
+ key file listed in the same line is removed after use, regardless if
+ volume activation was successful or not. This is useful if the key
+ file is only acquired transiently at runtime and shall be erased
+ before the system continues to boot.
+
+ * There's also a new /etc/crypttab option "try-empty-password". If
+ specified, before asking the user for a password it is attempted to
+ unlock the volume with an empty password. This is useful for
+ installing encrypted images whose password shall be set on first boot
+ instead of at installation time.
+
+ * systemd-cryptsetup will now attempt to load the keys to unlock
+ volumes with automatically from files in
+ /etc/cryptsetup-keys.d/<volume>.key and
+ /run/cryptsetup-keys.d/<volume>.key, if any of these files exist.
+
+ * logind.conf gained a new RuntimeDirectoryInodesMax= setting to
+ control the inode limit for the per-user $XDG_RUNTIME_DIR tmpfs
+ instance.
+
+ * systemd-firstboot gained a new --root-password-hashed= parameter for
+ setting the root user's password as UNIX password hash. There's a new
+ --delete-root-password switch which instead of setting a password for
+ the root user, removes it so that log-in without a password is
+ permitted. There's now --force which if specified means any existing
+ configuration is overwritten by the specified settings. It also
+ gained a new --kernel-command-line= parameter which may be used to
+ set the /etc/kernel/cmdline file of an OS image.
+
+ * A new generator systemd-xdg-autostart-generator has been added. It
+ automatically generates systemd unit files from XDG autostart
+ .desktop files, and is useful for allowing systemd to manage services
+ defined that way safely and automatically.
+
+ * systemd will now log about all left-over processes remaining in a
+ unit when the unit is stopped. It will now warn about services using
+ KillMode=none, as this is generally an unsafe thing to make use of.
+
+ * .socket units gained a new boolean setting PassPacketInfo=. If
+ enabled, the kernel will attach additional per-packet metadata to all
+ packets read from the socket, as ancillary message. This controls the
+ IP_PKTINFO, IPV6_RECVPKTINFO, NETLINK_PKTINFO socket options,
+ depending on socket type.
+
+ * A new boolean option AssignAcquiredDelegatedPrefixAddress= has been
+ added to the [DHCPv6] section of .network files. If enabled (which is
+ the default) an address from any acquired delegated prefix is
+ automatically chosen and assigned to the interface.
+
+ * "systemctl reboot" takes the option "--reboot-argument=".
+ The optional positional argument to "systemctl reboot" is now
+ being deprecated in favor of this option.
+
+ * Support for the .include syntax in unit files has been removed. The
+ concept has been obsolete for 6 years and we started warning about
+ its pending removal 2 years ago (also see NEWS file below). It's
+ finally gone now.
+
CHANGES WITH 245:
* A new tool "systemd-repart" has been added, that operates as an
sockets and other file system objects are generated taking the new
database into account.
+ * systemd/PID 1 accepts a new "systemd.show-status=error" setting, and
+ "quiet" has been changed to imply that instead of
+ "systemd.show-status=auto". In this mode, only messages about errors
+ and significant delays in boot are shown on the console.
+
* The sd-event.h API gained native support for the new Linux "pidfd"
concept. This permits watching processes using file descriptors
instead of PID numbers, which fixes a number of races and makes
* networkctl gained support for showing per-interface logs in its
"status" output.

with at least one session on a local VT are granted permission.
* When systemd sets up PAM sessions that invoked service processes
shall run in, the pam_setcred() API is now invoked, thus permitting
PAM modules to set additional credentials for the processes.
+ * portablectl attach/detach verbs now accept --now and --enable options
+ to combine attachment with enablement and invocation, or detachment
+ with stopping and disablement.
+
+ * UPGRADE ISSUE: a bug where some jobs were trimmed as redundant was
+ fixed, which in turn exposed bugs in unit configuration of services
+ which have Type=oneshot and should only run once, but do not have
+ RemainAfterExit=yes set. Without RemainAfterExit=yes, a one-shot
+ service may be started again after exiting successfully, for example
+ as a dependency in another transaction. Affected services included
+ some internal systemd services (most notably
+ systemd-vconsole-setup.service, which was updated to have
+ RemainAfterExit=yes), and plymouth-start.service. Please ensure that
+ plymouth has been suitably updated or patched before upgrading to
+ this systemd release. See
+ https://bugzilla.redhat.com/show_bug.cgi?id=1807771 for some
+ additional discussion.

+ virtualization, architecture, kernel command line, hostname
and machine ID.
* logind is now a lot more aggressive when suspending the
example, a line that creates /run/nologin).
* A new API "sd-resolve.h" has been added which provides a simple
- asynchronous wrapper around glibc NSS host name resolution
+ asynchronous wrapper around glibc NSS hostname resolution
calls, such as getaddrinfo(). In contrast to glibc's
getaddrinfo_a(), it does not use signals. In contrast to most
other asynchronous name resolution libraries, this one does
not reimplement DNS, but reuses NSS, so that alternate
- host name resolution systems continue to work, such as mDNS,
+ hostname resolution systems continue to work, such as mDNS,
LDAP, etc. This API is based on libasyncns, but it has been
cleaned up for inclusion in systemd.
when he over-mounts a non-empty directory.
* There are new specifiers that are resolved in unit files,
- for the host name (%H), the machine ID (%m) and the boot ID
+ for the hostname (%H), the machine ID (%m) and the boot ID
(%b).
