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.
PXE-installasjon bruker filene <computeroutput>/var/lib/tftpboot/debian-edu/install.cfg</computeroutput> og forhåndsutfyllingsfilen i <computeroutput> /etc/debian-edu/www/debian-edu-install.dat</computeroutput>. Disse filene kan endres for å justere rekkefølgen brukt under installasjon, f.eks. for å hindre flere spørsmål når man installerer over nettet. En annen mulighet for å oppnå det samme er å sørge for ekstra innstillinger i <computeroutput>/etc/debian-edu/pxeinstall.conf</computeroutput> og <computeroutput>/etc/debian-edu/www/debian-edu-install.dat.local</computeroutput>, og å kjøre <computeroutput>/usr/sbin/debian-edu-pxeinstall</computeroutput> for å oppdatere de genererte filene.
