One thing I forgot to tell Efraim about is that I got around to looking at nar support in diffoscope. I know this isn't essential as you can just unpack the nars, then compare (as I think guix challenge does), but I've been thinking this could make it easier to compare nars. Anyway, as part of this I proposed adding lzip support, since nars can be lzipped, that turned out to be quite easy: https://salsa.debian.org/reproducible-builds/diffoscope/-/merge_requests/106 I'm finding nar support a bit harder though, I've raised a merge request anyway to see if I can get any feedback: https://salsa.debian.org/reproducible-builds/diffoscope/-/merge_requests/107 Chris
