Yes, and I mentioned recently the idea of applying an incremental .zd file that wrote only the blocks that had been changed between the factory installed build and the deployment build. But I'm not sure if that needs any support at all from olpc-os-builder, it might be better thought of as an olpc-os-customiser. I do something like this with my local Ubuntu builds ... a minimal but bootable filesystem is made by my builder, and stowed away in a .tar.gz. Then that is used as input to the next stage, which can be run repeatedly. It's all done in a tmpfs, with disk caching of downloads. Tools are included to convert the .tar.gz output of each stage into .img or .zd. -- James Cameron http://quozl.linux.org.au/ _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
