That's an interesting and unexpected usecase of nixops. I wouldn't use nixops at all if you plan on doing this. Why not just start instance in the Amazon AWS Console or using the command line tools of AWS? (for ami's see https://nixos.org/wiki/NixOS_on_Amazon_EC2) > The initial install goes > fine.

Can you give us the AMI that was used (see AWS Console or commandline tools) ? Also, how did you copy the contents of /etc/nixos/* to /root/nixcfg ? I have never seen this behavior before, and tested something similar yesterday successfully. Cheers, Rob -- Rob Vermaas [email] rob.verm...@gmail.com
