this is an operator to keep the hass UTM VM started

hass-svc.sh - the script which implements healthchecking and restarting svc.log - status log hass-svc.command - wrapper to start hass-svc at login, set in System Settings > Login Items > Open at Login

note, this all is convoluted and an imperfect solution, but good enough for now
