“pacman -Syu”“可能”破壞了我的系統，因為引導未安裝

我在 RaspberryPi2 上運行 4.9.61-1-ARCH armv7l。我透過升級破壞了我的系統。為了修復這個問題，我從另一個 Arch ARM 安裝中使用 chroot 進入 sdc2，但由於能力不足，我沒有掛載引導分割區 sdc1。我運行了pacman -Syu，現在我的系統再次啟動，並且只要我能告訴就運作良好，但是我收到以下警告：

另一個人pacman -Syu告訴我“沒什麼可做的”

現在我想知道這是否會導致問題，也許會導致未來的升級。是否建議降級 linux-raspberrypi 並再次運行升級，或者我在這裡安全嗎，因為它似乎有效？

資料夾 /boot 內容的修改日期與啟動分割區的修改日期相匹配，因此我按照註釋中的建議複製了它們 - 工作正常。

答案1

首先，將 /boot 中的所有內容複製到暫存目錄，

$ sudo cp -R /boot /tmp/boot
$ ls /tmp/boot # verify that everything copied over

然後刪除/boot中的所有內容，

$ sudo rm -ir /boot/*

然後掛載你的啟動目錄，

$ sudo mount -a # mounts all filesystems mentioned in fstab
$ sudo mount | grep boot # verify boot is mounted

然後將所有內容複製回/boot，

$ sudo cp -R /tmp/boot/* /boot/
$ ls /boot # verify files copied over successfully
$ sudo rm -rf /tmp/boot # delete temporary directory
