| Hello, I can’t find any solution on the internet so I’m reaching you by email. I’m trying to achieve netboot on one of my devices. To do so I made a dedicated image: truncate -s 10G debian-nbd.img mkfs.btrfs debian-nbd.img sudo mount -t btrfs -o loop debian-nbd.img /mnt rsync -avPAHXxe path/to/existing/debian/rootfs /mnt sudo umount /mnt [node] exportname = /path/to/debian-nbd.img And I edited /etc/nbd-server/config: [generic] user = root group = root I restart nbd-server I provide PXE boot to my device thanks to the following file content: LABEL Armbian [NBD] MENU LABEL Armbian [NBD] KERNEL /srv/tftp/2c546b9f5bc2ee5d/Image INITRD /srv/tftp/2c546b9f5bc2ee5d/uInitrd FDT /srv/tftp/2c546b9f5bc2ee5d/rk3588s-rock-5c.dtb APPEND root=/dev/nbd0 nbdroot=192.168.1.46,10809,node rw ip=dhcp rootwait ipv6.disable=1 When powering my device, here is the output I get: [ 20.867028] Run /init as init process Loading, please wait...

Gave up waiting for root file system device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Missing modules (cat /proc/modules; ls /dev) ALERT! /dev/nbd0 does not exist. Dropping to a shell! (initramfs) Moreover here is the output of the master server journalctl -F: Feb 06 16:01:30 rpi nbd_server[82115]: Spawned a child process Feb 06 16:01:30 rpi nbd_server[82123]: Negotiation failed: Connection reset by peer Feb 06 16:01:30 rpi nbd_server[82123]: Exiting.
