Relying on an /etc/hostid file which is installed in the system image breaks diskless systems which share an image. Certain cluster infrastructure such as MPI relies on all nodes having a unique hostid. However, we still must be careful to ensure the hostid is syncronized between the initramfs and system images when using zfs root filesystems. To accompish this the automatically created /etc/hostid file has been removed from the spl rpm packaging. The /etc/hostid file is now dynamically created for your initramfs as part of the dracut install process. This avoids the need to install it in the actual system images. This change also resolves the spl_hostid parameter handling for dracut.
