Thanks!

The first production use:

https://autobuilder.yocto.io/pub/repro-fail/oe-reproducible-20200215-t1s21q9r/packages/diff-html/

:)

That's great!

I am a bit puzzled/concerned about how this hasn't been removed from
the system yet as it should have been, unless its the hashequiv problem
with timestamps continuing to cause problems. Need to fix my patch...

It looks like a directory ordering issue to me, since the timestamps are the same. One way to really flush these out would be to use disorderfs (https://salsa.debian.org/reproducible-builds/disorderfs) which permutates the order in which entries are listed in a directory, but I think we should try to get "wider" coverage (more recipes) before we try that.

Cheers,

Richard
