【Ubuntu】客户ubuntu文件系统定制使用说明

1.在开发板的UBUNTU系统上面安装软件rsync : sudo apt-get install rsync

2.在开发板的UBUNTU系统上面安装软件openssh的服务端openssh-server并修改root登录权限 : 
sudo apt-get install openssh-server
sudo vi /etc/ssh/sshd_config
修改PermitRootLogin选项用以确保root登录权限足够

重启开发板或者重启ssh服务（/etc/init.d/ssh restart）

3.PC端安装openssh客户端openssh-client
sudo apt-get install openssh-client

4.PC端安装rsync
sudo apt-get install rsync

5.通过rsync
新建目录ubuntu_make ：
mkdir ubuntu_make 
cd ubuntu_make
在PC端当前目录新建ubuntu目录：mkdir ubuntu 
同步数据：sudo rsync -avx root@开发板IP:/ ubuntu/
开发板IP为客户端通过ifconfig确认
6.在ubuntu文件夹下面增加文件etc/onlyone.sh
sudo vi etc/onlyone.sh
内容为：
#!/bin/sh

read line < /proc/cmdline
for arg in $line; do
        if [ "5" -le "$(expr length $arg)" ]; then
                if [ "root=" = "$(expr substr $arg 1 5)" ]; then
                {
                        debug_arg=$(expr $arg : 'root=\(.*\)')
                        resize2fs $debug_arg
                }
                fi
        fi
done 
更改文件权限sudo chmod 777 etc/onlyone.sh
使用脚本打包UBUNTU系统：拷贝make_ubuntu.sh到当前文件夹
7制作ubuntu固件：
./make_ubuntu.sh ubuntu
制作ubuntu_core:
./make_ubuntu.sh ubuntu_core
如下图所示分别为ubuntu_core和ubuntu固件：

 8.附上make_ubuntu.sh脚本内容：

2. #!/bin/bash
4. #ubuntu(ubuntu-core) build already annotation
5. #not Often compiled .......too slow and need root
6. MAKE_THEARD=`cat /proc/cpuinfo| grep "processor"| wc -l`
