* pid1: also remove PID files of a service when the service starts, not just
when it exits
+* systemd-path: add ESP and XBOOTLDR path. Add "private" runtime/state/cache dir enum,
+ mapping to $RUNTIME_DIRECTORY, $STATE_DIRECTORY and such
+
* make "systemd-dissect" an official supported tool, i.e. move to /usr/bin/ and
provide man page. Given that we now have a tool that can generate images like
this, it's useful to have one that can dump contents of them, too.
