我在我的 RaspberryPi2 上运行 4.9.61-1-ARCH armv7l。我通过升级它破坏了我的系统。为了修复它，我从另一个 Arch ARM 安装中使用 chroot 进入 sdc2，但我没有挂载引导分区 sdc1 是因为无能。我跑了pacman -Syu，现在我的系统再次启动，并且只要我知道就可以正常运行，但是我收到以下警告：

另一个pacman -Syu告诉我“无事可做”
现在我想知道这是否会导致问题，也许与未来的升级有关。是否建议降级 linux-raspberrypi 并再次运行升级，或者我在这里安全水域，因为它似乎工作？
/boot 文件夹内容的修改日期与引导分区的修改日期相匹配，所以我按照评论中的建议复制了它们——工作正常。
