Subject: [PATCH] core: update setings on the unit and job as the result of
505ca8
 ExecCondition=
505ca8
505ca8
Update ExecCondition= to set Unit->condition_result and return JOB_DONE
505ca8
in the Job results  if the check fails so as to match the current behavior
505ca8
of ConditionXYZ= w.r.t units/jobs dependency checks.
505ca8
505ca8
Fixes: #18207
