Diskless network boot NBD root
Boot from a NBD root device
This article will explain how to boot an ArchLinux Installation from a Network Block Device (NBD).
Much of the work to be done is based on the article Diskless network boot NFS root, so this will be referenced several times within the article.
Advantages over NFS
The main advantages are that NBD is faster and that you can boot from an encrypted or LVM-based NBD root device. One disadvantage is that you cannot update your kernel from within the running diskless client, although this may be worked around by mounting /boot via NFS.
