通过Wayland terminal运行dbus-lanuch程序报错
1.开发板连接显示器；
2.打开Wayland terminal;
3.在该终端上设置环境：export PATH=$PATH:/usr/sbin:/sbin
4.在该终端上运行dbus-lanuch，出现/usr/bin/dbus-daemon没权限访问题：
“Failed to execute message bus daemon /usr/bin/dbus-daemon:Permission denied.”
5.而且会发现其他各种访问问题，例如运行命令：cd ~ 也会报错

首先是处理一下文件系统的挂载权限:

adb shell uname -a
adb shell cat /firmware*/v*/v*
adb shell "cat /proc/mounts | grep ext4" 
adb shell mount -o remount,rw /
adb shell "cat /proc/mounts | grep ext4" 

如果还是不行, 就修改disable掉verity权限:

adb wait-for-device root
adb disable-verity
adb reboot
adb wait-for-device root
adb shell mount -o remount,rw /
adb shell "cat /proc/mounts | grep ext4" 

如果还是不行, 我们就关闭selinux:

adb root
adb shell setenforce permissive
