Instead, the entire image is loaded into the RAM of the ThinClient machine. - The disadvantage is that your ThinClient now needs at least 1 GB of RAM. + 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 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. Also, making changes/updating the NFS-based TCE was rather finicky - with the current TCE, 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. We've also received reports that the old NFS-based TCE wouldn't work with Jessie, or at least it was very hard to get it to work. Our current TCE 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 contains all the required functionality of live-build by then. + + ===== ThinClient prerequisites for all variants ===== + * At least 1 GB of RAM + * At least an i586-compatible CPU + * Capability to boot via PXE /or/ sufficient local storage (expect 250-450 MB, depending on what you decide to include) ===== Build system prerequisites for all variants ===== * You need a Debian Jessie system to build the image.
