This is how I do it, and gsbuild does something similar if I remember correctly. The binaries are installed one on top of the other in the / system. However, at the end of each iteration, a copy of the relevant directories is put in a temporary location for later analysis. This requires a lot of space since if you did 2 build iterations, you'd have essentially 3 copies of the system: The actual final system in / The iter1 system in /some_temp_dir/iter1 The iter2 (same as final) system in /some_temp_dir/iter2 One other thing is that /tools/bin (or whatever you call /tools) is removed from the PATH for any ITER>1. It should be unnecessary at this point and would identify any serious flaws in your system. I should have just done this the first time, but I'm attaching the actual functions file I source in my scripts. There is a bit more housekeeping in the top level build script for changing the location of the LOGDIR, STAMPDIR and anything else you don't want to clobber, but I think you'll get the idea. Hopefully you don't get too bogged down by unreferenced function names and parameters. do_(ica|farce)_prep is called at the end of the iteration. This first calls do_ica_files which copies the files to the temp location. Then all the stripping, etc. is done. After all the iterations are done, a for loop counting ITER up to ITERATIONS calls do_(ica|farce)_work on ITER and ITER+1 to do the actual diffing on the temporary locations. -- Dan
