This sounds like a very intrusive change that in the worst case could introduce errors and expose user data to permanent loss without any means to recover. Many tools read and write zip files. The actual ZIP standard format is controlled by (coordinated by) PKZIP via their application note. There is a lot of discussion about common extensions, but each tool can have their own private extensions that may be incompatible. The InfoZIP team that gives you the zip and unzip tools has added support for the bzip2 and lzma compression and decompression algorithms, as well as AES encryption/decryption in their upcoming beta release. I've been involved in reworking U*IX build support, and working towards better support on mainframe platforms (z/OS, z/VM) and AIX. I do all my primary development and testing on Fedora, but others have their own preferred platform. This implementation has been built and extensively tested using the current release of the real bzip2 library. Substituting a completely different library implementation without going through extensive and explicit validating and testing is risky and unreasonable. At best, it would complicate problem reporting, reproduction, analysis and correction. The libzip effort is not part of the InfoZIP project. They may have created a wonderful library, but it will not have identical interfaces and behaviours as the original bzip2 library. Let the upstream tools decide which bzip implementation(s) to support, and do the necessary validation to ensure that it all works correctly. It is the upstream tool's reputation that would be damaged if the Fedora library caused user data to be lost. Let them do their job correctly. Final gloomy thought of the day: Breaking zip files could you are breaking the actual tool used for backups. That makes data loss a very permanent problem.
