Description Joshua Lock 2017-03-17 15:07:26 UTC 
Pass options to tar, et al, to write archives with deterministic metadata (clamp uid & gid to 0, stable timestamp, etc).

Some archive formats don't provide this functionality OOTB, for those we should consider other techniques to ensure the archives are deterministic across builds.

will be part of the "reproducible binaries" patch set.
Comment 2 Juro Bystricky 2017-08-30 23:40:12 UTC 
There have been some incremental progress. Generally, archive commands (tar, gzip) are scattered all over. Several patches were accepted that fix some of the issues, but there are a few more left. Some patches are still pending/being reviewed in ML. So moving to 2.5 M1 for completion, as more patches are to follow before this can be closed as RESOLVED.
Comment 3 Juro Bystricky 2018-05-15 11:18:44 UTC 
I am closing this as this has been either implement or superseded by more specific problems.
