I was trying to install IBM i (mostly) over the network, and ran into some difficulties setting it up. IBM provides some information on netboot, the most important being how you set up an image catalog – that is, an NFS share with a VOLUME_LIST file at its root listing the files. However, it doesn’t mention how the NFS share should be set up (assuming you’re not using IBM i to host it), and what files should be in that volume list.
