vi /var/lib/tftpboot/pxelinux.cfg/default 启动界面在这修改
default linux # 默认启动的是 'label linux' 中标记的启动内核
prompt 1 # 显示 'boot: ' 提示符
timeout 60 # 等待超时时间，单位为 1/10 秒,超时后自动启动 默认指定的label
display boot.msg # 显示boot.msg的内容，文件路径是相对tftp server 的根目录(默认 /tftpboot),所以boot.msg文件绝对路径在 /tftpboot/boot.msg
menu.c32 提供类菜单模式的功能
pxelinux.0 开机管理程式
pxelinuxcfg 开机的选单设定
vesamenu.c32 图形化界面菜单
vmlinuz 安装软件核心文档（kernel file）
initrd.img 开机过程所需要的模块参数
isolinux.cfg -->demo 作为pxe所需开机菜单
--size 规范分割的大小
--grow 系统自动去判断最大可用容量，然后通通分给该分区
--asprimary 将该分割强制列在主要分割类型中
--grub-crypt rootpw密码获取
