I have a setup where a Raspberry 3 boots with PXE and mounts an iSCSI volume as rootfs with
iscsid. Now, it seems there is no way to cleanly reboot since there is the network chicken and the rootfs egg that would have to be cleanly released simultaneously. The device just hangs without actually rebooting or halting.
Is there a Raspberry-specific way to short-circuit the boot protocol to cut power uncleanly without caring for results or a clean way to fix systemd?
