在archlinux上挂载nfs服务器的一个目录，命令：
sudo mount -t nfs -o nolock 192.168.43.101:/home/xxx/E9231C8DF/e /xxx
报错：
mount: /xx: fsconfig system call failed: NFS: mount program didn't pass remote address.
dmesg(1) may have more information after failed mount system call.
原因：
用showmount -e ip 查看，报错没有命令
安装pacman -S nfs-utils 之后showmount正常显示，mount也正常了
