Hello,
I would like to have livenet / nbd plugins to be present on the initram disk of Fedora Workstation Live DVD, but I struggle to find a place where to send a patch. Can you help me where should I file this? Must be some dracut script that builds those, or is this the official kernel that ships with Fedora system?
These modules are small, but it will offer possibility to boot Fedora Live via PXE from network (HTTP, FTP or NBD). It has few dependencies (nbd-client, curl) but those are tiny and I assume curl is already in the minimal installation anyway.
Use case: A neighbour shows up with a broken Windows laptop without a CD/DVD drive apparently and I have no USB stick with up-to-date Fedora Live image handy. With my proposal implemented, I can offer connecting to my network, booting up Fedora and to try things out. In dozens of minutes, new happy Fedora user walks out of my doors :-)
I would like to carry on with a change to livecd-tools providing helper script livecd-to-pxe-livenet and livecd-to-pxe-nbd to help with creating those configurations.
If this turns to be a bad idea, then I will design the helper scripts to generate the kernel/image from a running system, but then users need to run compatible distro to successfully generate it.

All Fedora Editions use the official kernel and the nbd driver is already built. You likely want to contact the Workstation WG on the desktop to see about getting the dracut modules included, though you might simply request it to be included in all of them. I don't see why you wouldn't want similar functionality for Server.

I think rel-eng is changing the tooling it uses to create the live images. You might want to review this:

I'm not sure what you mean by "generate the kernel" here.

dracut itself contains the configuration about what modules get built into the initramfs in what situations. Live images use a generic (--no- hostonly) initramfs. I'd talk to the dracut maintainer about the appropriate way to add these.

Hmm, it looks like dracut-live contains the module livenet and dracut-network contains nbd module. But where is the place with the list of plugins to be included for workstation live spin? Can't find these.
I don't believe we include all the plugins as on Fedora 23 Live there is no "livenet" module from what I understand (does not work for me).

It's probably defined in the lorax template [1] which is part of what live-media-creator uses. Currently for F-23 we actually use livecd-creator but in F-24 we'll be moving to lmc because it then uses the same code paths etc as the rest of the tools we use to build the distro so that's where the change should land.

Ok, thanks. It looks like livenet is already included by default, so I expect to have it in F24 then.
