@Tom-Elliott I really appreciate that you are putting effort into providing more frequent releases, which makes it easier for everyone to deploy new security fixes in time. Keep up the good work!
The idea of fog client is to rename the host based on what you name the computer within FOG, not the other way around.
If you want it to be a specific name, and you have the FOG Client installed, set the wanted name in the FOG UI, and the host will change automatically.
