[Nix-dev] hack the source, then install

No, but you can run make install and test without making
/nix/store/your-package valid (is this still true after making the store
read only) - at least in the past it was possible.

You can try something else:

export DISPLAY=:0.0; rxvt

then hack in that shell. If you drop the hack you'll get a new clean
hash - thus you don't mess up the store.
