There is a memory leak in portablectl #23481

# portablectl detach --runtime --enable --now /root/t1
(Matching unit files with prefix 't1'.)
Queued /org/freedesktop/systemd1/job/1479 to call StopUnit on portable service t1.service.
Removed "/run/systemd/system.attached/t1.service".
DetachImage failed: No unit files associated with '/root/t1' found attached to the system. Image not attached?
