FAI 3.1.6 was just uploaded and is now available in the repository from my URL deb http://www.informatik.uni-koeln.de/fai/download etch koeln It fixes a grave bug in fai-class, that did not set HOSTNAME and so most classes were not defined. So if you are using FAI 3.1.5 you should upgrade to 3.1.6 soon. -- regards Thomas
