I don't know if its a good idea to require an initramfs for mounting a rootfs over the network. NFS root is currently in the kernel, and frequently used without an initramfs. Booting from ceph using a root device is relatively simple compared to generating an initramfs and it has the possibility of producing smaller images for memory constrained devices. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
