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。
