Features:
+* extend device cgroup controller support to allow enabling groups of
+ device nodes, so that pts can be allowed in whole. For that,
+ introduce the syntax "block-XYZ" and "char-XYZ" in addition to the
+ existing "/dev/foobar", where XYZ then is looked up in /proc/devices
+ and mapped to one or more majors.
+
+* Add all pts device nodes to those allowed by default when the device
+ controller is used.
+
* "busctl status" works only as root on dbus1, since we cannot read
/proc/$PID/exe
