It + implements an SNTP client. In contrast to NTP + implementations such as chrony or the NTP reference server + this only implements a client side, and does not bother with + the full NTP complexity, focussing only on querying time + from one remote server and synchronizing the local clock to + it. Unless you intend to serve NTP to networked clients or + want to connect to local hardware clocks this simple NTP + client should be more than appropriate for most + installations. The daemon runs with minimal privileges, and + has been hooked up with networkd to only operate when + network connectivity is available. The daemon saves the + current clock to disk every time a new NTP sync has been + acquired, and uses this to possibly correct the system clock + early at bootup, in order to accomodate for systems that + lack an RTC such as the Raspberry Pi and embedded devices, + and make sure that time monotonically progresses on these + systems, even if it is not always correct. + + * The "seqnum" interface of libudev has been disabled, as it + was generally incompatible with device namspacing as + sequence numbers of devices go "missing" if the devices are + part of a different namespace. + + * "systemctl list-timers" and "systemctl list-sockets" gained + a --recursive switch for showing units of these types also + for all local containers, similar in style to the + --recursive switch "systemctl list-units" already supports. + + * A new RebootArgument= setting has been added for service + units, which may be used to specify a kernel reboot argument + for usage when triggering reboots with StartLimitAction=. + + * A new FailureAction= setting has been added for service + units which may be used to specify an operation to trigger + when a service fails. This works similar to + StartLimitAction=, but unlike it controls what is done + immediately rather than only after several attempts to + restart the service in question. + + * hostnamed got updated to also expose the kernel name, + release and version on the bus. This is useful for executing + commands like hostnamectl with the -H switch. + + * The bootchart tool can now show cgroup information in the + graphs it generates. + + * The CFS CPU quota cgroup attribute is now exposed for + services. The new CPUQuota= switch has been added for this + which takes a percentage value. Setting this will have the + result that a service may never get more CPU time than the + specified percentage, even if the machine is otherwise idle. + + * systemd-networkd learned IPIP and SIT tunnel support. + + * LSB init scripts exposing a dependency on $network will now + get a dependency on network-online.target rather than simply + network.target. This should bring LSB handling closer to + what it was on SysV systems. + + * A new fsck.repair= kernel option has been added to control + how fsck shall deal with unclean file systems at boot. + + * The (.ini) configuration file parser will now silently + ignore sections whose name begins with "X-". This may be + used to maintain application-specific extension sections in unit + files. + + * machined gained a new API to query the IP addresses of + registered containers. "machinectl status" has been updated + to show these addresses in its output. + + * A new call sd_uid_get_display() has been added to the + sd-login APIs for querying the "primary" session of a + user. The "primary" session of the user is elected from the + user's sessions and generally a graphical session is + preferred over a text one. + + * A minimal systemd-resolved daemon has been added. It + currently simply acts as a companion to systemd-networkd and + manages resolv.conf based on per-interface DNS + configuration, possibly supplied via DHCP. In the long run + we hope to extend this into a local DNSSEC enabled DNS and + mDNS cache. + + * Two new service options StartupCPUShares= and + StartupBlockIOWeight= have been added that work similar to + CPUShares= and BlockIOWeight= however only apply during + system startup. This is useful to priorize certain services + differently during bootup than during normal runtime. + + Contributions from: Ali H.
