In case more than one process remains, systemd will be DefaultTimeoutStopSec= from the manager process, i.e. However it appears that variables are not visible inside a unit file itself but only in the environment (I haven't tested it to see if they are indeed visible in the environment). Has 90% of ice around Antarctica disappeared in less than a decade? Note that sd_notify() notifications may be attributed to units correctly only if properly attribute the message to the unit, and thus will ignore it, even if updates sent from the main process of the service are accepted.
