This is very true, but to be brutally honest when you look at these differences below, I can't see any of the traditional distros ever winning on size, because Alpine is a different order of magnitude compared to them. If minimal size is the user's primary goal we're not even in the same contest as Alpine. That means we have to win on some other metric with the remaining users, for whom size is not the primary driving factor. We have to at least not look terrible size-wise compared to other traditional distros, which means we need to be as close as practical to Ubuntu / Debian (slim). IMHO even then we would need the default "fedora" image to be the minimal one, as that's what a casual user will compare, unless they happen to know "fedora-minimal" exists. > To get an idea on how Fedora does compared to some other distros > > REPOSITORY TAG IMAGE ID > CREATED SIZE > registry.fedoraproject.org/fedora rawhide 5e91f1acac7d 47 > hours ago 187 MB > registry.fedoraproject.org/fedora-minimal latest 438d4fec7485 5 > days ago 119 MB > docker.io/library/debian latest 4a7a1f401734 7 > days ago 119 MB FWIW, there's also debian:stable-slim at 72 MB > registry.opensuse.org/opensuse/leap latest 1a798c6c690f 5 > days ago 108 MB > docker.io/library/ubuntu latest 7e0aa2d69a15 3 > weeks ago 75.1 MB So we need to cull 45 MB / 36% of 'fedora-minimal' to reach this target, or 112 MB / 60% of 'fedora'. util-linux is a decent sized chunk of that, so makes sense to question its need. > docker.io/library/alpine latest 6dbb9cc54074 4 > weeks ago 5.88 MB Regards, Daniel -- |: https://berrange.com -o- https://www.flickr.com/photos/dberrange :| |: https://libvirt.org -o- https://fstop138.berrange.com :| |: https://entangle-photo.org -o- https://www.instagram.com/dberrange :| _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx 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@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
