系统启动后自动登录 kiosk 用户，直接进入 Chromium kiosk 模式，且禁用常见退出快捷键。

下面是整合了自动登录到 tty1（修改 /etc/inittab 自动登录）并且保持你的配置逻辑的完整脚本。

脚本说明

• 自动创建用户 kiosk
• 安装 Chromium、xbindkeys、unclutter、xinit 等依赖
• 配置 .xbindkeysrc 和 .xinitrc，启动 Chromium kiosk 并屏蔽 Alt+F4、Ctrl+W、Alt+Tab
• 修改 /etc/inittab 使 tty1 自动登录 kiosk，无密码提示
• 禁用 slim 自动登录，避免登录管理器干扰
• 启动时 kiosk 用户自动 startx，进入 Chromium kiosk

补充

• 用户登录后会自动进入图形界面启动 Chromium，且快捷键被屏蔽
• 你可以修改 $CHROMIUM_URL 变量为你的目标网址
• 如果想完全无桌面环境，避免启动 slim 桌面管理器，这个方案是最直接的
