Installing to shared storage
Using the shared storage strategy on the Hardkernel ODROID-C4 can be done by
shared.disk-image.img to an SD card or eMMC.
# dd if=shared.disk-image.img of=/dev/XXX bs=1M oflag=direct,sync status=progress
Due to device tree issues, using UEFI boot (i.e. booting an ISO off USB) is not currently useful as the boot media may not be detected, and internal storage (SD or eMMC) will definitely not be detected.
