【nfs】Not starting nfsd: no support in current kernel

看不到 nfsd 的进程在执行：
ps -ef | grep “nfsd”

不过nfsd的模块是有装载的。
ubuntu@linux-lab:/$ lsmod | grep nfsd
nfsd 499712 24
auth_rpcgss 135168 1 nfsd
nfs_acl 16384 1 nfsd
lockd 102400 1 nfsd
grace 16384 2 nfsd,lockd
sunrpc 557056 32 nfsd,auth_rpcgss,lockd,nfs_acl

看不懂这段，

/etc/init.d/nfs-kernel-server

case "$1" in
  start)
        export_files="/etc/exports"
        for file in /etc/exports.d/*.exports ;
