Well, perhaps its useless to point out, but for the sake of completeness I will, nonetheless 😉
Firefly itself is perhaps capable of running on the NAS – what specific device is this?
This would of course more elegantly elude your problem 🙂
You are right, but in this case I fear there are no chance of installing software on the device, although it runs some sort of Linux. It is an Intel SS4000-E four-disk device. It would be great if it could run from there but I believe it is not possible – if you know of a way, I’d be happy to learn about it.
Looks like a fairly standard machine running redboot. Should be pretty hackable if you wanted to.
