I have realized that earlier I forgot to add --user to systemd-run. To
my surprise, it does not work if I set
BUS_SESSION_BUS_ADDRESS="unix:path=/run/user/1000/bus" instead of
XDG_RUNTIME_DIR. I expected that the former is required for systemd-run.
This command works from a root shell prompt, I hope it should work
during resume as well.
It works :-)

Even during resume it goes into right slice.
