remove historic variants here as well

   * The client root filesystem is provided using NBD (Network Block Device). After each modification to the LTSP chroot the related NBD image has to be re-generated; run {{{ltsp-update-image}}} on the LTSP server.
  
  === Thin clients ===
- A thin client setup enables ordinary PCs to function as (X-)terminals. This means that the machine boots from a diskette or directly from the server using network-PROM (or PXE) without using the local client hard drive. The thin client setup used is that of the Linux Terminal Server Project (LTSP).

  Thin clients are a good way to make use of older, weaker machines as they effectively run all programs on the LTSP server. This works as follows: the service uses DHCP and TFTP to connect to the network and boot from the network. Next, the file system is mounted from the LTSP server using NBD, and finally the X Window System is started.
  The display manager (LDM) connects to the LTSP server via SSH with X-forwarding. This way all data is encrypted on the network.
