Every interactive prompt takes a var_<app>_<name> override and treats a closed stdin like Enter (`|| true`), so an install keeps going after the console that started it is gone. Values the script cannot do without end with exit 64 and name the variable to set. Validation loops stop asking when nobody can answer instead of spinning on an empty read.
