Sometimes you just need some kind of setup which is not so standard. This was the case which lead to this post. For some testing, I needed a minimal environment containing only a BusyBox shell and that was accessible via Dropbear SSH-server. Probably this setup is quite useless for daily use but it can be used as a base for testing with a minimum set of libraries available. Using this setup gives you the flexibility to experiment with a minimal environment without rebuilding small Linux images.
