(perhaps after doing a firmware update by rpi-update)

To use 'raspistill' and 'raspivid', to capture images from the pi-cam, you have to make symlinks -- they are missing by default:

ln -s /opt/vc/bin/* /usr/bin/
ln -s /opt/vc/lib/*.so /usr/lib/
situation: on kali-linux-1.0 (could not test kali-linux-1.0.4, due to incompatiblity of the micron-memorychip against the kali-provided /boot/ files, swapped kali-linux-1.0 /boot with the /boot from NOOBS)
