Features:
+* add systemctl stop --job-mode=triggering that follows TRIGGERED_BY deps and adds them to the same transaction
+
+* coredump logic should use prlimit() to query RLIMIT_CORE of the dumpee and honour it
+
+* Add a MaxRuntimeSec= setting for service units (or units in general) to terminate units after they ran for a certain
+ amount of time
+
+* Maybe add a way how users can "pin" units into memory, so that they are not subject to automatic GC?
+
* PID1: find a way how we can reload unit file configuration for
specific units only, without reloading the whole of systemd
