I'm going to try and get diffs of the remaining big package differences and see where we stand. The two big ones I know of are go as a language for reproducibility and perf. Perf will just be a shear pain to fix, hopefully the kernel will take patches. > One item is getting to the bottom of why it takes diffoscope beyond > the heat death of the universe to render its verdict on some items. That would be really helpful to get to the bottom of. The vim-common difference is actually really simple: https://autobuilder.yocto.io/pub/repro-fail/oe-reproducible-20210213-0djxo1sn/packages/diff-html/ so I don't know why it took 5 hours to compute that. It suggests something really silly/stupid is going on. diffoscope should be amenable to fixes so it would be worth talking to them too... (I have a fix for the locale problem in vim brewing, it needs a new buildtools-extended-tarball) Cheers, Richard
