从现有 Linux 系统上安装 Gentoo [云环境无 VNC]

基本思路和以前发过的从现有 Linux 系统上安装 Archlinux[云环境无 VNC] 差不多，主要就是在现有系统上先挂载 stage3,然后将磁盘挂在载第一层 chroot 下的/mnt/gentoo ，然后通过删除原系统、安装新 stage3 的方式实现。

Install Gentoo ON Exsit Linux without VNC

NO WARRANTY!!! BACKUP ALL YOUR DATA BEFORE OPERATING!

! Mount the disk to /mnt/gentoo

Actually, From the step, you can follow the Gentoo's Handbook to install the System !
