Yes, that is a thing on Wikipedia isn't it. ;) It's referring to a discussion held 5 years ago. > I > feel that eventually other filesystems may show to be better than > ext4 and we probably will need to change the standards for the sake > of quality.

I'll see your 5-year-old quote from the ext4 maintainer, and raise you a 1-day-old quote from a btrfs maintainer: "Just popping in here to say that btrfs is not ready to be default in Fedora yet. Optional is fine but not default. Thanks, Josef." If and when btrfs becomes a superior solution, I'm sure Fedora will be eager to ship it. -Eric -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
