To make BTRFS (or any new file-system) the default for a distribution will be really hard.
My thought on the subject: -1. IS IT STILL DESIRED TO MAKE BTRFS THE DEFAULT FILE-SYSTEM FOR FEDORA AT SOME (yet unknown) POINT IN THE FUTURE? 0. DETERMINE A ROOT FILE-SYSTEM CRITERIA (AND/OR a DEFAULT FS CRITERIA) * Does it exists somewhere in written and consolidated form? 1. DETERMINE CURRENT BTRFS STATUS (F18 ONWARDS) * See below. 2. EVALUATE IF 'CURRENT BTRFS STATUS' MEETS 'ROOT|DEFAULT FILE-SYSTEM CRITERIA' 3. ANACONDA: DETERMINE WHICH BTRFS FEATURES WILL BE SUPPORTED * Which raid levels, data, metadata, subvol, etc. Maybe some features will not be available or supported (either by a bug or by design). 4. ANACONDA: DETERMINE WHICH BTRFS DEFAULTS WILL USED * DEFAULTS FOR AUTOMATIC PARTITIONING with SCHEME as BTRFS * DEFAULTS FOR MANUAL PARTITIONING with SCHEME as BTRFS >> currently (and correct me if i am wrong): STANDARD PARTITIONS: for SWAP and /boot, / as btrfs 5. ANACONDA: HANDLE ALL BTRFS SIZE/FREE SPACE REQUIREMENTS * To be able to REJECT all Storage Configurations in which the resulting btrfs file-system will be too small and either fail or hit a known-bug/issue (which was declared non-blocker). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1. DETERMINE CURRENT BTRFS STATUS (F18 ONWARDS) A page similar to http://qa.fedoraproject.org/blockerbugs/milestone/18/final/buglist could be created to track 'BTRFS AS DEFAULT FS' status. Anybody interested in BTRFS as the default file-system for Fedora will be able to see at a glance how is that going. Bug-reports will be still filled against bugzilla. Tackers: * BTRFS_INSTALLER_SUPPORT Criteria TBD... (need input from Anaconda developers) DRAF: Any bug/issue that impacts the installer. * FS_RELIABILITY Criteria TBD... DRAFT: Any bug in which the file-system behaves erratically or incorrectly. Data Loss and Data Corruption are the worst example. * FS_PERFORMANCE Criteria TBD... (but as the name implies) DRAFT: Any bug that is NOT in FS_RELIABILITY in which the file-system is performing 'correctly' but its performance is not ok. * FS_MISC_ISSUES Criteria TBD... DRAFT: Any bug that is NOT in either FS_RELIABILITY nor FS_PERFORMANCE. Also it must not be on BTRFS_INSTALLER_SUPPORT. * BTRFS_ISSUES_QUEUE DRAFT: Anybody could mark any btrfs bug as blocking this. Then some assigned people can classify this queue and put them into any of the previous queues. * BTRFS_FEATURE_MAP DRAFT: A link to another page in which all btrfs features and possible configurations are rated: UNK | OK | ISSUE:MISC | ISSUE:PERF | ISSUE:REL | ISSUE:INST Example: BTRFS vXX MIRROR on VIRTIO: ISSUE:REL (very drafty) The idea of this is that one could see at a glance, which subset of features are the most problematic ones, and more. Something similar to: http://www.x.org/wiki/RadeonFeature ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ I know that it is a bit overkill, but maybe some subset of this could be done.
