Comment:
LTSP now uses NBD; add image update information.

  The LTSP servers are set up to receive syslog from thin clients and workstations, and forward these messages to the central syslog recipient. 
  
  Please note: Thin clients are using the programs installed on the server.
- Diskless workstations are using the programs installed in the server's LTSP chroot.
+ Diskless workstations are using the programs installed in the server's LTSP chroot, the client root filesystem is provided using NBD. 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).
