I do not know about the busybox question but in general to search
whether a process, say cdrdao, is present I would use a regexp that
matches the cdrdao command line but _not_ the grep command line itself:

<$>   ps auwwwwwwwwwwww|grep cdrdao
myuser   15160  0.0  0.4  1748  520 pts/27   R+   16:56   0:00 grep cdrdao
<$>  ps auwwwwwwwwwwww|grep [c]drdao

On the contrary, your regexp match itself, like the first of my two
examples above ...
