From matrix:
I need to exclude the "cpu" from the defaults: 'Default: memory,pci,net,serial,cpu,bios,monitor,scsi,usb,prom,sbus,sys,sysfs,udev,block,wlan'
nixos-facter segfaults when i try to run it with the default hardware strings, probably caused by a stupidly old vmware esxi hypervisor version on which the VM is running, excluding the "cpu" in the report generation prevents the segfault
