Anyone has working commands to get UEFI bootable Rockstor 3.9.1?

Hi,

I managed to install more ancient Rockstor with UEFI with instructions at:

However applying those to 3.9.1 I managed to only get “/dev/root missing”. Any help would be appreciated.

NVM, seems that I was ably to hack myself from the ancient version to current one since I didn’t need to worry about data.
