mingetty包

getty是Unix类操作系统启动时必须的三个步骤之一，用来开启终端，进行终端的初始化。
目前一般常用的getty程序有如下几种：
1.agetty（有时直接称为getty）：容易设置，无须配置文件。适用于直接连接的终端；
2.getty（getty_ps的一部分）：适用于直接连接的终端；
3.mgetty：最适合于通过modem连接，也可用于直连；
4.uugetty：仅用于通过modem连接终端，是getty_ps软件包的部分；
5.mingetty：简单的getty。适用于控制台终端或虚拟终端；
6.fbgetty：适用于控制台或虚拟终端。

修改/etc/issue中的内容，控制台登录显示不同的信息
