[Nix-dev] Do you think this is a possibility to speed up creating .nix-profile ?

[Marc Weber]

Michael Raskin has been right. Having an atomic operation is a design
goal. I've forgotten about that.
Anyway:

time cp -RP .nix-profile .nix-profile2
shows < 0.01s
so creating symlinks can't be the only thing taking time (I thought this
was the case while listening to the disks an watching the disk led)

So if I want to improve it I need to do some real benchmarking
