By running "nixos-checkout" and then passing "-I /path/to/my/sources" to
"nixos-rebuild".  ("nixos-checkout" probably should get a destination directory
argument, rather than always putting the trees in /etc/nixos.)

For instance, if I want to update my system to the latest NixOS version in the
NixOS channel, I do:

$ nix-channel --update
$ nixos-rebuild switch

But if I want to do a build from my local development tree, I do:

$ nixos-rebuild switch -I /home/eelco/Dev
