For specialised uses of the raspberry the generic and user centric components of the Operating System can get in the way.
So i decided to make my own init system: npStarter.
it is VERY simple and aimed at making the raspberryPI more like an embedded device.
The partitions are in read-only mode and everything writable is on temporary filesystems.
It can be turned off and on without worrying about filesystem/sd card corruption and starts working immediately when powered up.
I also created a cute little userland for it: npUserland. It can setup wifi and AP, jack, memcache and a couple of things i deemed useful.
