WD my cloud Goodsync

The busybox system basically rebuilds the root file system on every boot. There is a
way to get your changes applied after a reboot.
If you have a USB device attached to the My cloud. You can create two files. One called
fun_plug the other called mfg_WDMyCloud. The mfg_WDMyCloud file requires the following data.
mfg_WDMyCloud
sn00py

When the system reboots it looks for the mfg_WDMyCloud file and checks its contents. If things match
it will execute the fun_plug file. mfg_WDMyCloud is the name of the file on a single bay my cloud. If you look at the /usr/local/modules/script/system_init file on your system you will see that it does the following:
nas_model_name=xmldbc -g /hw_ver
The file that it looks for on the USB is called mfg_$nas_model_name. So you will need to change the WDMyCloud to what ever the nas_modle_name contains.
