=== Edgy specific setup ===

In edgy we began to install a default setup and themeing on the thin clients, to enable it, make sure your client environment is up to date through one of the above procedures and run:

 {{{
 sudo dpkg-reconfigure -pcritical edubuntu-artwork}}}

Beside the themes it will give you a default configuration with:

 * Local device support (please see also the ["EnableLTSP5LocalDevices"] page)
 * Network swapping
 * Sound support
 * 16bit colors to save bandwith
 * Centralized logging of the clients to the server

This page describes how you upgrade your LTSP client chroot on an upgrade to the next Edubuntu version

Warning /!\ Before following the notes below, make sure you have an up to date system on the Server, follow the UpgradeNotes wikipage for that.

While it is easy to just upgrade your client chroot to the recent package set, it is recommended to rather recreate the chroot to take advantage of all new features (some of them are set up during chroot creation, so you wont see them with a plain package upgrade).

Upgrading the client chroot

  • Copy your servers sources.list file into the chroot 
     sudo cp /etc/apt/sources.list /opt/ltsp/i386/etc/apt/sources.list
  • Update the package lists in the chroot 
     sudo chroot /opt/ltsp/i386 apt-get update
  • Upgrade the packages 
     sudo chroot /opt/ltsp/i386 apt-get dist-upgrade
  • Make sure the new client Kernel is used for tftpboot 
     sudo ltsp-update-kernels

After that procedure your LTSP clients have the most recent packages installed

Note for dapper->edgy upgrades local device support for thin clients was added, the package for this doesnt get installed on upgrades, so make sure to run: 

  •  sudo chroot /opt/ltsp/i386 apt-get install ltspfsd

to install it (also see the ["EnableLTSP5LocalDevices"] wikipage)

Recreating the client chroot (recommended)

  • Delete your old LTSP Client chroot 
     sudo rm -rf /opt/ltsp/i386
  • Create a new LTSP Client chroot 
     sudo ltsp-build-client

This will set up a new chroot automatically for you, after the command has finished you can just use your Thin Clients as usual.
