Apart from the rackd log, I have capture log before the PXE boot to the initramfs mode.
The last few lines are:
failure: overlayroot: failed to move root away from /root to /media/root-ro
mount: mounting /dev on /root/dev failed: No such file or directory
ipconfig: no device to configure
ipconfig: BOOTIF: SIOCGIFINDEX: No such device
wget: can’t connect to remote host (MAAS IP Address): Network is unreachable
