In a comment on the question Does Ubuntu deliberately contaminate its binaries to help NSA?, Jorge Castro notes that debian is thinking about working with reproducible builds. They state
Why do we want reproducible builds?
- Independent verifications that a binary matches what the source intended to produce.
- Help Multi-Arch: same packages co-installation (as they need every matching file to be byte identical).
- Be able to generate debug symbols for packages which do not have a “debug package”.
- Is there any indication that Ubuntu plans on implementing reproducible builds as well?
