We used '90' so far, so the module was linked +to '/usr/lib/dracut/modules.d/90dnbd3-rootfs'. + +Once the module has been integrated in dracut's modules, you can build +the initramfs with the following command: + + dracut --no-hostonly --modules "dnbd3-rootfs" <target_path> + +Note that the '--no-hostonly' is critical if the machine dracut is +executed on and the clients supposed to boot the resulting initramfs +differ. + +For more informations see: https://lab.ks.uni-freiburg.de/projects/dracut-praktikum/wiki |
