First I'd like to see there remaining BIOS metadata formats and RAID5 support. When graid will be finished and well tested, that can be done relatively easy (I'd say 1-2 days for each). Not sure it should fit into 9.0-RELEASE. > 2. Any timeframe for switching from the legacy ata(4) to the new infrastructure? I think we could do in one month: 1) graid needs at least some time to settle; 2) I need to reimplement SENSE data fetching in CAM for ATAPI/USB devices to user-level consumers via passX. That is needed to fix issues with some CD/DVD burning applications. Solution I have now is not ideal. 3) we should not delay it longer to let it settle before 9.0-RELEASE. If somebody knows other show stoppers or have ideas -- speak now. -- Alexander Motin
