installtointernal editable, location?

I know that installtointernal, while extremely useful, is not officially supported (?). So I would like to experiment a bit myself at my own risk.

1. Is it editable and what is the full file path? I tried the WinSCP Commands> Find Files> *installtointernal*.* from both /root and /storage and failed.

2. Is there a link to LE file structure for /and /storage with or without installtointernal ?

wget https://raw.githubusercontent.com/kszaq/LibreELEC.tv/libreelec-8.2/projects/S905/filesystem/usr/sbin/installtointernal

chmod +x installtointernal

./installtointernal

worked for me

Ok thanks.

But this looks like installing and running it.

How to edit it with say, nano? I would like to add a couple of copy instructions to it, e.g., copy to /flash/
