I wanted to do more tests and find some smaller reproducer, but I'm interested in this series. What I'm seeing in our builds is that when you compare files-in-image.txt report from independent (not reusing sstate-cache) builds with exactly the same metadata, group owners aren't deterministic. Random files in image getting owned by "messagebus" group etc., these issues went away when useradd class creating these ad-hoc groups had parameter for fixed gid or when I've added these groups directly to base-passwd group.master. Is this the same problem you're addressing in this patchset? > I'm confident patch 01/02 should be added to master. > > The patch 02/02 works properly in all of my testing and does implement > support > for 'deterministic uid/gid' with dynamic passwd/group file construction > during > package install.
