Reproducible builds are important for software supply chain security. See https://reproducible-builds.org/ All packages in Debian are tested for reproducibility. Currently the latest MariaDB 10.3 build in Debian fails due to the build of the Mroonga, RocksDB and TokuDB plugins. See https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/mariadb-1... I've filed issues about this at Mroonga and RocksDB now: https://github.com/mroonga/mroonga/issues/298 https://github.com/facebook/rocksdb/issues/6276 TokuDB does not seem to accept any issues anymore and there are no commits since 2015. The project is dead, right? https://tokutek.atlassian.net/projects/DB/issues https://github.com/percona/tokudb-engine
