You have to waste a usb drive to turn into drm garbage for licensing. They do obscure secret sauce shit to make mixed drives work… it’s far better to accomplish the same thing with mergerfs and snapraid as it’s open and documented properly. The whole spinning up docker containes by filling out web forms is just fucking gross.

If you want a server distro with a UI then UnRAID offers literally nothing over OpenMediaVault which is free and open source and offers far more control.
