[Nix-dev] Getting started with cloned nixpkgs: multiple errors and other questions

[Arseniy Seroka]

That's my workflow:
I have cloned repo in ~/nixpkgs
and I have `export NIXPKGS_ALL=~/nixpkgs`
When I do something in my repo and want to test it, I use
`nix-env -i foobar -f $NIXPKGS_ALL -K # that's to test installation of some
pkg`
(-K to save temp build directory)
and
`sudo nixos-rebuild switch -I nixpkgs=$NIXPKGS_ALL` # that's to test some
modules, services etc (something from `nixpkgs/nixos`)
