If this is a 1:1 host to image environment for the DSR you were talking about… I don’t know why you’d even need the fog client… unless you want it to deploy EXEs or MSIs or printers or such… or schedule reboots, shutdowns, etc. But a DSR’s purpose is not to deploy MSIs or shutdown computers, you know?
I say test this tomorrow, fully - with at least one computer. I wouldn’t risk downloading to the same computer, but perhaps to a same (or similar) model that you have as a spare.
If this doesn’t work, don’t fear, we have FOG Trunk that does work on Debian 8.
