The PXE installation uses the preseeding file <computeroutput>/etc/debian-edu/www/debian-edu-install.dat</computeroutput>. This file can be changed to adjust the preseeding used during installation, to avoid more questions when installing over the net. Another way to achieve this is to provide extra settings in <computeroutput>/etc/debian-edu/pxeinstall.conf</computeroutput> and <computeroutput>/etc/debian-edu/www/debian-edu-install.dat.local</computeroutput> and to run <computeroutput>/usr/sbin/debian-edu-pxeinstall</computeroutput> to update the generated files.
