The usage of `ps -l` is fragile and does not always return the expected set of columns. It differs even between several BusyBox versions and operating systems. Use `ps -o pid,ppid` to get the expected set of columns instead. Also kill parent first before its children to prevent spawning another command from clevisloop itself.
