I totally disagree. Busybox is very high quality software. What I would agree with is that it is infuriatingly limited for interactive shells... especially when you are used to bash and the full GNU suite. But be clear - that is not because of poor quality, only it is natural because Busybox is written with very different design constraints and goals - and for what it is intended to do - its brilliant. Absolutely brilliant. (Sorry my FUD alarm just threw a wobbly!)
