I came across the following old post, which I'm not responding to in-thread due to its age. https://www.redhat.com/archives/fedora-devel-list/2009-September/msg00517.html The question was raised why RPMs sign their compressed data, rather than uncompressed. (One advantage would be to avoid deltarpm rebuild failures due to changes in compression such as the recent one in xz.) The answer had to do with the fact that higher-level tools (createrepo and yum) depend on the current behavior, but that doesn't address whether it's just an early design mistake that we're locked into now, or if there's actually some overall advantage to doing things this way (that outweighs the obvious disadvantage of inflexibility in how the data is compressed). Can anyone shed some light on this? -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
