* The unified cgroup hierarchy added in Linux 4.5 is now supported.
Use systemd.unified_cgroup_hierarchy=1 on the kernel command line to
- enable.
+ enable. Also, support for the "io" cgroup controller in the unified
+ hierarchy has been added, so that the "memory", "pids" and "io" are
+ now the controllers that are supported on the unified hierarchy.
WARNING: it is not possible to use previous systemd versions with
systemd.unified_cgroup_hierarchy=1 and the new kernel. Therefore it
deployable. The systemd-nspaw@.service template unit file has been
changed to use this functionality by default.
+ * systemd-nspawn gained a new --network-zone= switch, that allows
+ creating ad-hoc virtual Ethernet links between multiple containers,
+ that only exist as long as at least one container referencing them is
+ running. This allows easy connecting of multiple containers with a
+ common link that implements an Ethernet broadcast domain. Each of
+ these network "zones" may be named relatively freely by the user, and
+ may be referenced by any number of containers, but each container may
+ only reference one of these "zones". On the lower level, this is
+ implemented by an automatically managed bridge network interface for
+ each zone, that is created when the first container referencing its
+ zone is created and removed when the last one referencing its zone
+ terminates.
+
* The default start timeout may now be configured on the kernel command
line via systemd.default_timeout_start_sec=. It was already
configurable via the DefaultTimeoutStartSec= option in
value is understood as UNIX nice value. If not prefixed like this it
is understood as raw RLIMIT_NICE limit.
+ * Note that the effect of the PrivateDevices= unit file setting changed
+ slightly with this release: the per-device /dev file system will be
+ mounted read-only from this version on, and will have "noexec"
+ set. This (minor) change of behaviour might cause some (exceptional)
+ legacy software to break, when PrivateDevices=yes is set for its
+ service. Please leave PrivateDevices= off if you run into problems
+ with this.
+
+ * The systemd-networkd DHCP server gained the option EmitRouter=, which
+ defaults to yes, to configure if the DHCP Option 3 (Router) should be
+ emitted.
