root partition wont allow to go lower, So I think its the smallest we can get.
But will try to cleanup the OS again, see if I can reduse more.
I think the only thing left to reduce size and improve stability (maybe?) is abandon Desktop
I thought the same thing but the problem is that nvOC is an easy to use mining system. I think it won't be easy to use for lots of people if you remove gnome desktop or another desktop interface. A lighter interface desktop would be a better solution.
