Comment 6 for bug 751531

The attached branch is just a proof-of-concept implementation, probably not suitable for merging as is. It runs a script inside the chroot, so it is limited in that it cannot copy files from the host into the rootfs. In comment #2 I have proposed some more flexible approaches.

@Tom:
Although both approaches will lead to the same result, I think they actually belong to different use cases.

My use case is that it is currently tedious to customize the produced images each time they are created, so I (as a developer) am deterred from trying them out on a regular basis. I think people would find it even more tedious to use live-build, so that they are able to install some additional development packages, set up the network, install synergy etc.

You are right that this isn't the right mechanism for producing "official" customized images and it is not my intention to promote this instead of the proper tool which is live-build. I believe that these approaches are complimentary, not conflicting.
