@Sebastian-Roth The variables you don’t recognize are part of post installation scripts, I haven’t modified any php classes.
I will see if I can get that output on monday, we’ve now deployed all of our surface go 1’s back to their users but I can probably nab one for a few minutes if I get in early enough.
I can also try a different ipxe boot file for good measure. I use ipxe.efi maybe snponly.efi will load things differently and yield different results
