+ two new unit types have been introduced:
- Scope units are very similar to service units, however, are
created out of pre-existing processes -- instead of PID 1
forking off the processes.
- Slice units may be used to partition system resources in an
hierarchial fashion and then assign other units to them. By
default there are now three slices: system.slice (for all
system services), user.slice (for all user sessions),
machine.slice (for VMs and containers).
+ new concept of "transient" units, which are created at runtime
using an API and not based on configuration from disk.
+ logind has been updated to make use of scope and slice units to
manage user sessions. Logind will no longer create cgroups
hierchies itself but will relying on PID 1.
+ A new mini-daemon "systemd-machined" has been added which
may be used by virtualization managers to register local
VMs/containers. machinectl tool has been added to query
meta-data from systemd-machined.
+ Low-level cgroup configuration options ControlGroup=,
ControlGroupModify=, ControlGroupPersistent=,
ControlGroupAttribute= have been removed. High-level attribute
settings or slice units should be used instead?
+ A new bus call SetUnitProperties() has been added to alter
various runtime parameters of a unit, including cgroup
parameters. systemctl gained set-properties command to wrap
this call.
+ A new tool "systemd-run" has been added which can be used to
run arbitrary command lines as transient services or scopes,
while configuring a number of settings via the command
