Subject: [PATCH] Fix boot loader when "$disk" is defined (#58)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Fix boot loader when "$disk" is defined

机器有两个盘：/dev/sda 和 /dev/vda ，添加参数--disk /dev/vda将系统安装至该盘，grub也需要安装至该盘，否则grub-install会出错。

* Update debi.sh
