fish很好用，所以删除zsh，但是忘记RootShell依然是zsh。

接着尝试了数十次正确密码无法登录，事实上是因为找不到Shell导致的失败orz

使用systemd-boot的话

Step 1: Reboot and Access systemd-boot

Restart your system

When the systemd-boot menu appears, press e to edit the current boot entry

Look for the kernel parameters line - it usually starts with something like linux /vmlinuz-... root=...

Step 2: Modify Kernel Parameters for Rescue Mode

Add rw init=/bin/sh at end

  • rw - mounts the filesystem as read-write
  • init=/bin/sh - tells the kernel to start sh instead of the normal init system

Step 3: chsh or reinstall shell

1
chsh -s /usr/bin/bash

Or

1
paru -Syu zsh
