It was a feature approved by FESCo to make it the default for Fedora 16 instead of ext4. http://meetbot.fedoraproject.org/fedora-meeting/2011-06-08/fesco.2011-06-08-17.30.log.html But this came with some criteria to be met before freeze, namely "btrfsck", which were not met and two months later Josef said it would not be the default. Since he subsequently left Red Hat, only Eric Sandeen has much Btrfs knowledge, but he works mainly on the RHEL kernel and doesn't have time to help maintain Btrfs stuff for the very new kernels Fedora uses beyond what upstream does. And for that matter, no one upstream intends for serious regressions to happen in Btrfs, yet they can and do happen. So the catch-22 with Fedora kernels being so new, is anyone using Btrfs is going to be among the first users to experience bug fixes, feature enhancements as well as regressions. I don't know that having an experienced Btrfs kernel developer on the Fedora kernel team would matter that much in preventing regressions from landing as Fedora stable kernels. Rather, it'd probably take an increase in time to stable or increase in karma value to delay the unknown, until better known. openSUSE uses Btrfs by default (except for /home) but they'd also using much older kernels with cherry picked backported bug fixes. Even if Fedora had a Btrfs dev I don't foresee Fedora running 3-4 major versions of the kernel behind, just to make Btrfs the default. -- Chris Murphy -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
