When creating reproducible builds, nuances such as exact dependency matching, using an immutable set and versions of the build tools, identical sets of options and defaults, preservation of file build order (using the same sorting methods), and disabling the addition of compiler non-deterministic metadata, such as random values, file path references, and build date and time information, are taken into account. Build reproducibility is also affected by bugs and race conditions in the toolchain. <\/p>\n
