I am trying out the new feature of 7.3.0-rc1, booting from an internal drive. However that seems to count as using a device. I have the Unraid OS Starter license for 6 devices. I have attached 2 nvme's and 4 hdd drives, and before i was using a flash drive to boot. Do i have to go back to using the flash drive ?! Or if i want to keep using internal boot, i need to purchase a upgraded license ?
