[Nix-dev] nix-shell enhancements

[Marc Weber]

Well - I have one command

nI -A foo

which builds foo by attr with -K flag.
If the build fails, it cds into the build directory.
I then have a second command to start a new terminal window
so that I can load nix-env.

That's all I need for debugging.

If I need more I add a "fail" to a build phase, and run the others
manually.
That's my way :)

You talk about git and rollbacks. What about .o files? Will they be
committed so that you can "rollback" ? You should clarify such details.
