嵌入式文件系统一般用户执行su root切换根用户提示错误:
su: must be suid to work properly

解决方法:
修改busybox权限,chmod 4755 busybox

0 15:20$ must be suid to work properly
-bash: must: command not found
127 15:20$ chmod 4755 busybox
chmod: busybox: No such file or directory
1 15:21$ cd /
0 15:21$ chmod 4755 busybox
chmod: busybox: No such file or directory

没有那个文件或目录!

1 15:22$ sudo find -name busybox
./.cdl/initrd/bin/busybox
./bin/busybox
0 15:22$ chmod 4755 ./bin/busybox
chmod: ./bin/busybox: Operation not permitted
1 15:23$ sudo chmod 4755 ./bin/busybox

再执行su root就可以了。

但在CDLinux下不知道root用户密码,好像是没有密码,

直接执行:sudo su 就可以了。
