Yea and the best part was that installing NixOS was dead easy. I followed Graham Christensen's instructions[1] and had nix create a personalized image with the latest linux kernel and some other stuff. Then I just flashed and booted from that image after partitioning. Honestly it was dead simple and its so hard to go back to the ad-hoc system config style a la Arch linux and other distros.
I'm probably a lost cause now because I think I'm going to convert my entire raspberry pi cluster to NixOS from ubuntu.
