Don't be afraid; there aren't many. We have done a good job of hiding the complexity of Debian during the installation and beyond. However, Debian Edu is Debian, and if you want there are more than 57,000 packages to choose from and a billion configuration options. For the majority of our users, our defaults should be fine.

The amount of packages fetched from the net varies from profile to profile but stays below a gigabyte (unless you choose to install all possible desktops). Once you have installed the main-server (whether a pure main-server or combi-server does not matter), further installation will use its proxy to avoid downloading the same package several times from the net. </para></section></section><section><title>Installation using USB flash drives instead of CD / Blu-ray discs</title><para>It is possible to directly copy a CD/BD <code>.iso</code> image to USB flash drives (also known as "USB sticks") and boot from them.

When clients boot via the main network, an iPXE menu with installer and boot selection options is displayed. If PXE installation fails with an error message claiming a XXX.bin file is missing, then most probably the client's network card requires nonfree firmware. In this case the Debian Installer's initrd must be modified. This can be achieved by executing the command:  <code>/usr/share/debian-edu-config/tools/pxe-addfirmware </code> on the server. </para><para>This is how the iPXE menu looks with the <emphasis role="strong">Main-Server</emphasis> profile only: </para><para><inlinemediaobject><imageobject><imagedata fileref="https://wiki.debian.org/DebianEdu/Documentation/Bullseye/Installation?action=AttachFile&do=get&target=30-Main-Server-GRUB_Boot_menu-PXE.png"/></imageobject><textobject><phrase>width=400</phrase></textobject></inlinemediaobject> </para><para>This is how the iPXE menu looks with the <emphasis role="strong">Main Server</emphasis> and <emphasis role="strong">LTSP Server</emphasis> profiles: </para><para><inlinemediaobject><imageobject><imagedata fileref="https://wiki.debian.org/DebianEdu/Documentation/Bullseye/Installation?action=AttachFile&do=get&target=28-Diskless-WS-GRUB_Boot_menu-PXE.png"/></imageobject><textobject><phrase>width=400</phrase></textobject></inlinemediaobject> </para><para>To install a desktop environment of your choice instead of the default one, press TAB and edit the kernel boot options (like explained above).  </para><para>This setup also allows diskless workstations and thin clients to be booted on the main network.

These files 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 <code>/etc/debian-edu/pxeinstall.conf</code> and <code>/etc/debian-edu/www/debian-edu-install.dat.local</code> and to run <code>/usr/sbin/debian-edu-pxeinstall</code> to update the generated files.  </para><para>Further information can be found in the <ulink url="https://www.debian.org/releases/Bullseye/installmanual">manual of the Debian Installer</ulink>. </para><para>To disable or change the use of the proxy when installing via PXE, the lines containing <code>mirror/http/proxy</code>, <code>mirror/ftp/proxy</code> and <code>preseed/early_command</code> in <code>tjener:/etc/debian-edu/www/debian-edu-install.dat </code> need to be changed.  To disable the use of a proxy when installing, put '#' in front of the first two lines, and remove the "<code>export http_proxy="http://webcache:3128"; </code>" part from the last one. </para><para>Some settings can not be preseeded because they are needed before the preseeding file is downloaded.  These are configured in the PXElinux-based boot arguments available from <code>/srv/tftp/debian-edu/install.cfg</code>.  Language, keyboard layout and desktop are examples of such settings. </para></section><section><title>Custom images</title><para>Creating custom CDs, DVDs or Blu-ray discs can be quite easy since we use the <ulink url="https://wiki.debian.org/DebianInstaller/">Debian Installer</ulink>, which has a modular design and other nice features. <ulink url="https://wiki.debian.org/DebianInstaller/Preseed">Preseeding</ulink> allows you to define answers to the questions normally asked.  </para><para>So all you need to do is to create a preseeding file with your answers (this is described in the appendix of the Debian Installer manual) and <ulink url="https://wiki.debian.org/DebianInstaller/Modify/CD">remaster the CD/DVD</ulink>. </para></section></section><section><title>Screenshot tour</title><para>The text mode and the graphical installation are functionally identical - only the appearance is different.
