rk3399 9.0 boot and execute .sh file

Function: Create a folder in the /sdcard/ root directory after booting. Since the /sdcard/ mount is completed after the system is booted, it can only be achieved by executing the sh file at boot.
1.First define the service, add the service definition and start in device/rockchip/common/init.rk30board.rc

service customer_service /vendor/bin/sh /vendor/bin/customer_service.shclass late_startuser rootgroup rootdisabledoneshotseclabel u:r:customer_sevice:s0on property:sys.boot_completed=1start customer_service

2. Give the corresponding permissions for the service

Add in device/rockchip/common/sepolicy/vendor/file_contexts

/vendor/bin/customer_service.sh u:object_r:customer_service_exec:s0

Add customer_service.te file under device/rockchip/common/sepolicy/vendor/

type customer_service, domain;type customer_service_exec, exec_type, vendor_file_type, file_type;init_daemon_domain(customer_service)allow customer_service vendor_shell_exec:file rx_file_perms;allow customer_service system_file:file rx_file_perms;

3. Add the customer_service.sh file as follows

#! /vendor/bin/shsleep 10mkdir -p /sdcard/Configuration

Among them, sleep 10 is to mount /sdcard/ after the system is started. This is necessary, otherwise it cannot be created successfully.
