Sure, as the PXE image did boot fine, but where missing networking drivers, and some packages we use for 3D rendering I thought that it would be possible to build that from the live-server iso that did have all this…
But unfortunately I failed at it, and as I don’t have more time on this project I went back to CentOS.
I will try more with the Azure image, as I know we will spin up around 700 machines there soon for rendering.
The reason for pushing an PXE installer similar to CentOS ‘kickstart or better is to be able to run the same OS on both cloud and local computes.
And yeah, to spice things up a bit, the PXE server is an Windows Deployment server with a pxelinux mini hack on top 
On my initial tests, ClearLinux did perform 10-15% better at 3D rendering.
