  ===== History, Rationale, Outlook =====
  
- During the time of Debian Wheezy being Debian's stable release, we started developing a new ThinClientEdition then called TCE-NG - one that is based on Debian-Live and thus does no longer rely on NFS.  Instead, the entire image
is loaded into the RAM of the ThinClient machine.  To avoid confusion, and because it now has left the "NG" state, we call it TCE-Live.
+ During the time of Debian Wheezy being Debian's stable release, we started developing a new ThinClientEdition then called TCE-Next Generation, or TCE-NG for short - one that is based on Debian-Live and thus does no longer rely on NFS (though NFS can still be used to deploy the image - but we strongly discourage that approach).  Instead, the entire image is loaded into the RAM of the ThinClient machine.  To avoid confusion, and because it has since left the "NG" state, we now call it TCE-Live.
  
  The disadvantage is that your ThinClient now needs at least 1 GB of RAM (see below).  
  
- However, the huge advantage is that there no longer is a need for any high-availibility setup concerning NFS.  All you need is an HTTP (HTTPS optional for later stages) or FTP server with a dedicated IP, if you want to use netbooting.  It is also possible to deploy
the image to the ThinClient's local storage, if present, and have it update in the background.  Besides, making changes/updating the NFS-based TCE (henceforth referred to as TCE-NFS or TCE-Legacy) was rather finicky - with the current TCE-Live, you build and deploy a new image every time you make a change, and you can test it on a single client without interrupting your production environment.  The "local storage" feature can also be used to create a portable version of both X2Go-TCE and X2goClient for Windows, sharing the same configuration, on CD/DVD/USB media.

If you follow our advice of loading the entire image into the ThinClient's RAM, or using local storage,  all you need is an HTTP (HTTPS optional for later stages) or FTP server with a dedicated IP, if you want to use netbooting.

- We've also received reports that TCE-NFS wouldn't work with Jessie, or at least it was very hard to get it to work.
+ Besides, making changes/updating the classic, NFS-based TCE (henceforth referred to as TCE-Classic) with the entire filesystem, not just its compressed image, spread out over the NFS share was rather finicky - with the current TCE-Live, you build and deploy a new image every time you make a change, and you can test it on a single client without interrupting your production environment.

  Our TCE-Live works just fine with Jessie, and we expect it to work in Stretch and hopefully in Buster (Stretch+1) as
well.
  The one catch is that the live-build package in Debian/the Debian-Live project is currently looking for a new maintainer - so there is a slim chance that live-build might be removed from Debian Buster, especially if no new maintainer steps up and the live-build replacement that is currently in the works (called live-wrapper) contains all the required functionality of live-build by then.
