I recently participated in the PIWEBAPI lab at the EMEA users conf. in London. (Great Lab!) As a participant I received a RaspberryPi with a temperature sensor to test with at home. It was installed with Debian and a preset user "pi" with password "piwebapi123", however I didn't receive the "root" password and am unable to run any "su" commands. The setup on the RaspberryPI for the lab was great and I don't want to a reinstall Debian. Does anybody know the "root" password?
