Workstation Autoinstall Preseed

This is a full Preseed file that will install a Ubuntu Desktop. It's the actual preseed we use, with some specifics removed.

There are two additional scripts used for the final stages. You can find them here: Enterprise/WorkstationAutoinstallScripts

Here's how to integrate use Cobbler for installation over the network: Enterprise/Cobbler

Notes

  • It's localised for Switzerland
  • You need to adapt it and fill in some blanks
  • It's designed so it doesn't ask any questions. It will wipe the entire disk.
  • The disk is fully encrypted with a temporary password that is replaced in the final script
  • It is based on the official example-preseed

Explanation

The Setup is designed as a one-time setup. Without configuration management.

There are two scripts.

Script 1: Additional System Confguration:

This script is executed directly after installation, before shutdown. There I add some additional software and sources. If an nvidia-graphics card is detected, I install the proprietary driver (nvidia-current-updates), by default Ubuntu installs the open source nouveau driver and on first login asks for installation of additional drivers.

Skript 2: User-setup:

Script 2 is a interactive script which runs in a X screen where I use zenity for user Input. It is started by a custom upstart job which hooks in on "starting-dm" i.e. before lightdm (login-screen) is started. The script then launches the X Server, and a gnome-terminal on the X screen, which launches the same script again with "stage2" as parameter, that's the part with the graphical queries.

Disk Encryption:

The Preseed file sets a temporary password. And in the User Setup script, a Sys-Admin has to enter the default password, which is veryfied by the hash. Then the temporary password is replaced with the default admin password and the users password is added as an additional passphrase. Like that we have the same admin password on every machine (for emergency access or whatever).
