[Bug 1950996] Re: Missing all modules for usb nics in initrd which makes PXE boot impossible

[Dan Czuchra]

Hi all, are there any updates to this issue? This has broken our 20.04
builds over iPXE. We're trying to update the initrd and vmlinuz files,
but there's not very good documentation on how to update these files.

Bug description:
  initrd taken from the live iso for PXE boot does not contain USB NIC
  drivers which makes PXE installation/netboot impossible via usb.

  This is the case on 20.04 server iso (both hwe and normal
  kernel/initrd) and desktop iso.

  "kernel/drivers/net/usb" is empty and needs to be included in the
  initramfs build.

  As most modern thin laptops lack physical rj45 ethernet this is a big
  issue.
