PXE：在 /root/dev 上安装 /dev 失败

我正在尝试 PXE 启动 Debian 11，但遇到了一个非常奇怪的问题；很奇怪，因为直到今天早些时候它都运行良好。然后我做了一个小更改（安装了 nfs-common 并在 /etc/fstab 中进行了更改以挂载远程 NFS 共享）。

现在 grub 菜单出现 - 这是菜单项：

menuentry 'Debian 11' {
  set background_color=black
  linux /debian11/boot/vmlinuz-5.10.0-27-amd64 console=tty0 console=ttyS0 ip=dhcp root=/dev/nfs ro nfsroot=192.168.50.111:/image/debian11,vers=3,nolock panic=60 ipv6.disable=1 rootwait ignore_loglevel
  initrd /debian11/boot/initrd.img-5.10.0-27-amd64
}

内核启动了，但在中间，它出现了恐慌：

这个 grub 配置工作得很好，无论如何，在内核启动之前都会调用 init-bottom 脚本，是吗？那么为什么它死得这么晚呢？
