Doesn't work because as a copy of the USB linux install drive, pkgs/ will not have *deb files on it.

This gist was intended to be used on a live system. If you want the resulting local repo to on the installer image and available during an install, you'll have to do more than what's here.

Probably a better idea than this gist is to use the aptly tool, which is a lot better at making and managing Debian repos. Create a repo using aptly on a separate server and then use a preseed file in your install which sets up this server as another repository. At that point, you can also add custom packages to get install using the preseed, etc. It's a lot easier to do this than to manipulate the installer image by adding files to it.
