The SUSE Linux Enterprise team is working towards providing reproducible builds - packages which can be recreated exactly across multiple builds and different machines. At the moment, most of SUSE's packages will build in a reproducible fashion. A post covering the status of reproducible builds in openSUSE and SUSE Linux Enterprise (SLE) states: "Currently 263 of 10,650 Factory packages have major reproducibility issues. Another 305 have minor issues that are already ignored by build-compare. So those are good from the OBS point of view, but they do not give perfect bit-identical results yet. There are also 31 packages that I found to not build in 15 years from now. This timescale is relevant for maintaining an enterprise distribution. Because many users pick up new versions slowly and are reluctant to do major upgrades. However, packages built in Tumbleweed, are not fully reproducible, yet. This is because they contain the build time and build hostname in rpm headers. Probably because people feel that they want to know. Possibly in case there is some problem with a certain build host, it makes it easier to track the issue."
