如何制作最简单和最小的Linux系统

1、光盘挂载
    mount /dev/cdrom /mnt/

2、安装febootstrap命令
    yum install febootstrap

3、制作镜像目录
    febootstrap -i bash  -i yum  centos6 centos6.4_base file:///mnt/

4、将locale-archive文件进行缩减，原有98M，之后1.6M
    cp /usr/lib/locale/locale-archive /tmp/
    rm -fv /usr/lib/locale/locale-archive && localedef -f UTF-8 -i zh_CN zh_CN.UTF8 && localedef --list-archive
    cp /usr/lib/locale/locale-archive centos6.4_base/usr/lib/locale/

[root@localhost  ~]# cp -a /root/.bash* centos6.4_base/root/
[root@localhost  ~]# du -sh centos6.4_base/
49M     centos6.4_base/
[root@localhost  ~]# cd centos6.4_base/ && tar -c .|docker import - centos6.4_min
