This is true, I finally got Luma and emunand working. I updated my emunand to the latest firm with no problems. But I did make sure that my emunand and sysnand weren't linked (not sure if it really matters).
After using using this site for 3 or 4 years I finally decided to join. WARNING, I suck at grammar, so don't be rude because of it. I know that people here can be mean and can be nice. I hope to get along with everyone I come across =)
