The experiment had a flaw: I did not do the builds as -j1 (or no -j at all) but the parallel activities changes the sequencing of the lines from run to run. Thus the "diff -u" part finds more differences than I was intending. I may try to make a better experiment at some point. > After having done installworld installkernel for other reasons, > I did two -dM buildworld buildkernel sequences in a row (no > source changes, no cleaning activity), producing script files > logging the output.
