为了在播放机上实现NFS服务器的功能，我们已经在uClibc中打开了完整RPC支持，并且在新编译的内核中打开了NFS服务器支持。此外还有两个软件包也是提供NFS服务所必需的：
portmap
和
nfs-utils
。portmap为RPC程序提供端口映射服务，nfs-utils则是使用内核NFS服务器的支持程序。
编译portmap
1. 下载portmap_5beta: ftp://ftp.porcupine.org/pub/security/portmap_5beta.tar.gz
2. 打这个补丁: portmap_5beta.patch.zip （补丁来自buildroot-2009.11，我只是把多个补丁合并成一个）
3. $ make CC=mipsel-linux-gcc
4. $ mipsel-linux-strip portmap
编译nfs-utils
1. 下载nfs-utils-1.1.1: http://nchc.dl.sourceforge.net/project/nfs/nfs-utils/1.1.1/nfs-utils-1.1.1.tar.gz
2. 打这个补丁: nfs-utils-1.1.1-uclibc.patch.zip （在网上找到的，来源记不清了，我稍加了修改）
3. 运行配置脚本：
1

在制作固件时，我们只需要几个编译好的程序： portmap, rpc.statd, rpc.nfsd, rpc.mountd, exportfs。其中 portmap 放到 /sbin下，其余的放到 /usr/sbin下。
此外还需要一个NFS服务启动脚本S60nfs，放在/etc/init.d目录下。下载脚本 S60nfs.zip (来自buildroot，我把portmap的启动加进去了）
