At this step, apply the following changes: - /media/isoimage/isolinux.cfg 23:59:20.000000000 +0200 The steps above will start vi to edit the isolinux configuration file. Sudo mkisofs -r -V "Custom Ubuntu Netboot image" -cache-inodes -J -l -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /tmp/CustomMini.iso /tmp/miniiso_remastered/ Sudo vi /tmp/miniiso_remastered/isolinux.cfg Sudo mount mini.iso /media/isoimage -o loop
#UBUNTU MINI ISO EXPERT INSTALL INSTALL#
Download the mini.iso file of the distribution you would like to install (tested with hardy-proposed on, hardy currently suffers from ) to /tmp and proceed as follows: cd /tmp In order to make your life easier (typing URLs at the isolinux prompt is not my favourite task), you can modify the iso image to include the URL and some options which cannot be set from the preseed file in the default boot options.
#UBUNTU MINI ISO EXPERT INSTALL PASSWORD#
This preseed file assumes that you have a DHCP server on your network and sets the password for the installation user to SECRET123. d-i debconf/priority select criticalĭ-i network-console/password password SECRET123ĭ-i network-console/password-again password SECRET123ĭ-i preseed/early_command string anna-install network-console Copy a file with the following content to a webserver which is reachable by the machine you want to set-up.

In order to tell the debian installer to start the ssh server and wait for you to connect, it needs a preseed file (see ). The installation medium will be a CD / DVD containing an (optionally modified) netboot mini.iso image as found on. Choose one and then connect via ssh using the installer user and the password you have chosen.Īfter connecting via ssh you can change the debconf priority back to 'critical' to make the installation easier by suppressing optional questions asked by the installer.

One of the next steps should be a question asking for the SSH password. That will set your debconf priority to low automatically.Īs soon as you come to a screen presenting you a list of installer components which can be loaded, tick network-console: Continue installation remotely using SSH and continue. If you use the netboot iso, simply boot by entering expert instead of the default install. Select Change debconf priority and choose low. If you use the alternate installation CD, you have to boot the system and press escape as soon as the installer presents you the first question. The rest of the guide is split into these two parts. The first option involved less work on your part, but the person starting the installation will need a helping hand if he/she is not familiar with the Debian Installer. Modify the netboot iso and automate the installation up to the point where you can connect via SSH.Use the standard alternate installation CD or the netboot mini iso and ask someone to go through the network configuration.This procedure works for the standard debian ncurses installer, not for the graphical installer on the Ubuntu Desktop Live cd. You can then use an ssh client to connect to the installation and proceed as if you were sitting in front of the machine. The approach outlined here starts an ssh daemon right after the network configuration of the debian installer. Many server systems provide console access over the network, but if the server you have to set-up does not, things tend to become difficult. Occasionally you may have to install a system which you cannot access physically. This is a work in progress, it is not mature yet and it may break your system!Īs you may already have guessed, following the instructions may break your system and you are on your own to fix it again.
