[Nix-dev] NixOS on a machine with only one user

scalable result, and in most cases the additional cost is very close to 
zero. For example every single-disk system I set up uses a two-disk RAID 
array with one missing disk from the point of view of mdadm. If it does 
happen that I actually want to add more disks, it will be a few short 
online commands to do it instead of a tedious reinstallation of the 
entire system, and it costs only a few megabytes. The additional disk 
might as well be an external emergency disk that starts synchronising as 
soon as I plug it in.

How did you manage to make mdadm do that?
