Ok so installing #talos from a usb stick didn’t work as it wanted to use the stick as the system disk. Had to image directly on to the internal SSD.
Still, the first worker node is up and running. Couple more to get going. All eBay HP EliteDesk Mini G2s with an i5-6500 processor and 16GB.
Will be selling some 8GB #raspberryPi 4s in a couple of weeks after the upgrade. If you are in the UK and interested let me know…
