I am downloading the various aarch64 8.5 images. Focusing on minimal and dvd. I will be putting it somehow on a usb stick and need to find out how the Odroid will recognize it My Odroid/HC4 is enroute; should be here in a day or two so what to do some planning. How does the iso image install figure out where to put the partitions? Until I learn how, I suspect I will be putting the /boot on the mSD card after the uboot. HardKernel (maker of Odroid) has a larger uboot that some devices. How do I insure that the partition does not step on it. Is RAID1 built in? The HC4 has 2 sata slots and I will be putting identical 2.5" HD in them. Would like to use RAID1. I would like to place the / partition on the HDs. That should be fairly straight-forward with extlinux.conf append like: append root=UUID=ad25a528-baf4-469c-bd12-5276e8f5f9ae What would this look like with RAID1? I am going to be rooting ( :) ) around the Odroid/HC4 wiki for how to boot an alternative OS iso and put down the uboot, but need to look at this from both sides. thanks
