I recently got my paws on a shiny new ReadyNAS Duo, and I LOVE it so far.  Setup in my Mac system went beautifully and I can't wait to test out all of its features, now that I've perused all the settings, manual, etc. 

For now, I'm especially curious about how the setup goes on a Linux system.  One great thing about it is that all three systems (Mac OS X, Linux, Windows) are supported and there are installation materials for all three on the included disk. 

Have you set up a ReadyNAS Duo in your Linux system?  Do you also have an EVA8000 integrated in with your Linux system?  I'd love to hear about your experiences, especially since I'd like to try Ubuntu 8.04 in Boot Camp :)
