Yes, the deltarpm process depends on xz giving the same output when run by the consumer of the .drpm as when run by the producer. If not, then deltarpm gives a warning and ignores the .drpm -- the entire new .rpm must be downloaded. > > What would happen if a newer version of xz/lzma comes out which (for > example) produces better compressed output while still remaining > compatible with the file format and older decompression tools? Then there would be a "one-time" event where none of the .drpm could be used, until xz on the consumer machine matches (catches up to) xz on the producer machine. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
