• Start with a debian install with a few changes including a new hostname (/etc/hostname file changed)
  • Use SD card with eFlasher to backup eMMC -> USB stick: Success
  • Use SD card with eFlasher to restore USB -> eMMC: Proceeds with no problems
  • Power down, remove SD card, remove USB, Power up
  • Hostname has changed to NanoPi-Zero2 :x

How can I prevent that change?
