CHANGES WITH 217:
- * journalctl gained option -t/--identifier to match on the
- syslog identifier and --utc option to show timestamps in UTC
- timezone. journalctl now also accepts -n/--lines=all to
- disable line cap under a pager.
+ * journalctl gained the new options -t/--identifier= to match
+ on the syslog identifier (aka "tag"), as well as --utc to
+ show log timestamps in the UTC timezone. journalctl now also
+ accepts -n/--lines=all to disable line capping in a pager.
* Services can notify the manager before they start a reload
(by sending RELOADING=1) or shutdown (by sending
- STOPPING=1). This allows the manager to show the
- internal state of daemons and closes a race condition
- when the process is still running but has closed its
- d-bus connection.
+ STOPPING=1). This allows the manager to track and show the
+ internal state of daemons and closes a race condition when
+ the process is still running but has closed its D-Bus
+ connection.
- * Services with Type=oneshot do not have to have any
- ExecStart commands.
+ * Services with Type=oneshot do not have to have any ExecStart
+ commands anymore.
* User units are now loaded also from
$XDG_RUNTIME_DIR/systemd/user/. This is similar to the
/run/systemd/user directory that was already previously
supported, but is under the control of the user.
- * A timeout for the start of the system can be configured. The
- system can be configured to reboot or poweroff if the basic
- system default target is not reached before the timeout (new
- StartTimeoutSec=, StartTimeoutAction=,
- StartTimeoutRebootArgument= options).
+ * Job timeouts (i.e. time-outs on the time a job that is
+ queued stays in the run queue) can now optionally result in
+ immediate reboot or power-off actions (JobTimeoutAction= and
+ JobTimeoutRebootArgument=). This is useful on ".target"
+ units, to limit the maximum time a target remains
+ undispatched in the run queue, and to trigger an emergency
+ operation in such a case. This is now used by default to
+ turn off the system if boot-up (as defined by everything in
+ basic.target) hangs and does not complete for at least
+ 15min. Also, if power-off or reboot hang for at least 30min
+ an immediate power-off/reboot operation is triggered. This
+ functionality is particularly useful to increase reliability
+ on embedded devices, but also on laptops which might
+ accidentally get powered on when carried in a backpack and
+ whose boot stays stuck in a hard disk encryption passphrase
+ question.
* systemd-logind can be configured to also handle lid switch
events even when the machine is docked or multiple displays
generator will parse the resume= option on the kernel
command-line to trigger resume.
- * systemd-evcat input debugging tool has been added. It will
- print keys read for the input system and show modifier
- status.
-
- * systemd-modeset graphics debugging tool will show undulating
- rainbows on all connected displays.
-
- * A user console daemon systemd-consoled has been added. It is
- a preview, and will so far open a single terminal on each
- session of the user marked as Desktop=SYSTEMD-CONSOLE.
+ * A user console daemon systemd-consoled has been
+ added. Currently, it is a preview, and will so far open a
+ single terminal on each session of the user marked as
+ Desktop=systemd-console.
* Route metrics can be specified for DHCP routes added by
systemd-networkd.
- * SELinux context of socket-actived services can be set from
- the information provided by the remote peer
+ * The SELinux context of socket-actived services can be set
+ from the information provided by the networking stack
(SELinuxContextFromNet= option).
* Userspace firmware loading support has been removed and
minutes, but a warning will be printed after 1 minute to
help diagnose kernel modules that take a long time to load.
- * Udev rules can now remove tags with TAG-="foobar".
+ * Udev rules can now remove tags on devices with TAG-="foobar".
- * Readhead implementation has been removed. In many
+ * systemd's readahead implementation has been removed. In many
circumstatances it didn't give expected benefits even for
rotational disk drives and was becoming less relevant in the
- age of SSDs.
+ age of SSDs. As none of the developers has been using
+ rotating media anymore, and nobody stepped up to actively
+ maintain this component of systemd it has now been removed.
* Swap units can use Discard= to specify discard options.
Discard options specified for swaps in /etc/fstab are now
* The Password Agent protocol gained support for queries where
the user input is shown, useful e.g. for usernames.
- systemd-ask-password gained a new --echo option to turn
- that on.
+ systemd-ask-password gained a new --echo option to turn that
+ on.
+
+ * The default sysctl.d/ snippets will now set:
+
+ net.core.default_qdisc = fq_codel
+
+ This selects Fair Queueing Controlled Delay as the default
+ queueing discipline for network interfaces. fq_codel helps
+ fight the network bufferbloat problem. It is believed to be
+ a good default with no tuning required for most workloads.
+ Downstream distributions may override this choice. On 10Gbit
+ servers that do not do forwarding, "fq" may perform better.
+ Systems without a good clocksource should use "pfifo_fast".
+
+ * If kdbus is enabled during build a new option BusPolicy= is
+ available for service units, that allows locking all service
+ processes into a stricter bus policy, in order to limit
+ access to various bus services, or even hide most of them
+ from the service's view entirely.
+
+ * networkctl will now show the .network and .link file
+ networkd has applied to a specific interface.
+
+ * sd-login gained a new API call sd_session_get_desktop() to
+ query which desktop environment has been selected for a
+ session.
+
+ * UNIX utmp support is now compile-time optional to support
+ legacy-free systems.
+
+ * systemctl gained two new commands "add-wants" and
+ "add-requires" for pulling in units from specific targets
+ easily.
+
+ * If the word "rescue" is specified on the kernel command line
+ the system will now boot into rescue mode (aka
+ rescue.target), which was previously available only by
+ specifying "1" or "systemd.unit=rescue.target" on the kernel
+ command line. This new kernel command line option nicely
+ mirrors the already existing "emergency" kernel command line
+ option.
+
+ * New kernel command line options mount.usr=, mount.usrflags=,
+ usrfstype= have been added that match root=, rootflags=,
+ rootfstype= but allow mounting a specific file system to
+ /usr.
+
+ * The $NOTIFY_SOCKET is now also passed to control processesof
+ services, not only the main process.
+
+ * This version reenables support for fsck's -l switch. This
+ means at least version v2.25 of util-linux is required for
+ operation, otherwise dead-locks on device nodes may
+ occur. Again: you need to update util-linux to at least
+ v2.25 when updating systemd to v217.
+
+ * The "multi-seat-x" tool has been removed from systemd, as
+ its functionality has been integrated into X servers 1.16,
+ and the tool is hence redundant. It is recommended to update
+ display managers invoking this tool to simply invoke X
+ directly from now on, again.
+
+ * Support for the new ALLOW_INTERACTIVE_AUTHORIZATION D-Bus
+ message flag has been added for all of systemd's PolicyKit
+ authenticated method calls has been added. In particular
+ this now allows optional interactive authorization via
+ PolicyKit for many of PID1's priviliged operations such as
+ unit file enabling and disabling.
+
+ * "udevadm hwdb --update" learnt a new switch "--usr" for
+ placing the rebuilt hardware database in /usr instead of
+ /etc. When used only hardware database entries stored in
+ /usr will be used, and any user database entries in /etc are
+ ignored. This functionality is useful for vendors to ship a
+ pre-built database on systems where local configuration is
+ unnecessary or unlikely.
+
+ * Calendar time specifications in .timer units now also
+ understand the strings "semi-annually", "quarterly" and
+ "minutely" as shortcuts (in addition to the pre-existing
+ "anually", "hourly", ...).
