Yes, that is correct

I could try that, but I did not want to touch g_file_storage.
Instead I wanted to write my own block device driver which is used by

So the daemon would be connected to my driver then .. I don't know, that sounds
complicated.

No, I didn't, but now that you mention it i can see the similarities - I will
have a look.
