I actually spent half an hour looking into that yesterday as I got diverted into the details of how the filesystem compression stuff works, but all the references I found say xz consistently compresses better than zstd. zstd's advantages over xz are in *performance* (time taken to compress and decompress). So switching from xz to zstd seems like it would make things bigger, not smaller. It shouldn't be too hard to try this out - it's just one setting in lorax somewhere, but I gave up on this alleyway before figuring out exactly where to set it. -- Adam Williamson Fedora QA IRC: adamw | Twitter: adamw_ha https://www.happyassassin.net _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
