I looked into this, and would like to come up with a proposal. Most of the text was stolen from https://wiki.debian.org/DebianInstaller/NetbootPXE I left Steven's NetworkManager-based three-liner from above beside, but took the config from the wiki page, to have an example, that works for everyone (hopefully). I could think of something like this (it could be added as a new chapter 4.5.1 in https://d-i.debian.org/manual/en.amd64/ch04s05.html, replacing the note we have now in 4.5): ========snip======= / Note: / | In the past, we recommended to use tftpd-hpa. It's written by the same author | as the syslinux bootloader and is therefore least likely to cause issues. | Another good alternative is atftpd. | Documentation for these traditional packages is still available below. | | These days however, it turns out, that **dnsmasq** is a good and easy to configure | solution, uniting all the needed functionality in one server. \ \ end of note 4.5.1 Setting up dnsmasq as all-in-one solution for DHCP + TFTP Following is an example for /etc/dnsmasq.conf providing the same functionality as the method of installing and configuring of isc-dhcp-server and tftpd-hpa described below: ----------------------------------------------------------------- interface=eth1 domain=yourdomain.com dhcp-range=192.168.0.3,192.168.0.253,255.255.255.0,1h dhcp-boot=pxelinux.0,pxeserver,192.168.0.2 enable-tftp tftp-root=/srv/tftp pxe-service=x86PC, "PXELINUX (BIOS)", "pxelinux.0" pxe-service=X86-64_EFI,"PXE (UEFI)","grubx64.efi" # other UEFI type identifier, see RFC4578 section-2.1 pxe-service=2, "PXELINUX (0002-EFI)", "grubx64.efi" pxe-service=6, "PXELINUX (0006-EFI)", "grubx64.efi" pxe-service=7, "PXELINUX (0007-EFI)", "grubx64.efi" pxe-service=8, "PXELINUX (0008-EFI)", "grubx64.efi" pxe-service=9, "PXELINUX (0009-EFI)", "grubx64.efi" ----------------------------------------------------------------- Download the netboot.tar.gz and extract it in the /srv/tftp (for trixie in this example): ----------------------------------------------------------------- cd /srv/ mkdir tftp cd /srv/tftp wget http://ftp.debian.org/debian/dists/trixie/main/installer-amd64/current/images/netboot/netboot.tar.gz tar -xzvf netboot.tar.gz rm netboot.tar.gz ln -s debian-installer/amd64/grubx64.efi . ln -s debian-installer/amd64/grub . ----------------------------------------------------------------- Then restart dnsmasq : systemctl restart dnsmasq and you should be able to start performing the installation. ========snap======= Holger
