systemd System and Service Manager
+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.
+
+ * 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.
+
+ * Services with Type=oneshot do not have to have any
+ ExecStart commands.
+
+ * 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).
+
+ * systemd-logind can be configured to also handle lid switch
+ events even when the machine is docked or multiple displays
+ are attached (HandleLidSwitchDocked= option).
+
+ * A helper binary and a service have been added which can be
+ used to resume from hibernation in the initramfs. A
+ generator will parse the resume= option on the kernel
+ command-line to trigger resume.
+
+ * 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.
+
+ * 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
+ (SELinuxContextFromNet= option).
+
+ * Userspace firmware loading support has been removed and
+ the minimum supported kernel version is thus bumped to 3.7.
+
+ * Timeout for udev workers has been increased from 1 to 3
+ 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".
+
+ * Readhead 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.
+
+ * Swap units can use Discard= to specify discard options.
+ Discard options specified for swaps in /etc/fstab are now
+ respected.
+
+ * Docker containers are now detected as a separate type of
+ virtualization.
+
+ * 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.
+
+ * 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".
+
