I hope Dragonfly will :produce the same kinds of synergies with the FreeBSD Project that our :ongoing relationships with NetBSD, OpenBSD, and various Linux projects :have. I'm especially interested in seeing you succeed with your :package management goals, where many other attempts have failed in :that area. : : For our part, we're planning to release FreeBSD 4.9 with PAE support :merged at the beginning of September. We certainly haven't ruled out :further 4.X releases after that time either. As usual, our release :related plans are available from http://www.FreeBSD.org/releng. : : Good luck, : : - Murray Thanks Murray. For the record, it is my intention to incorporate whatever work is committed to the FreeBSD-4 branch for as long as it is possible to do so. Even though the CVS trees are not compatible (I started mine as a fresh non-branched import), I very carefully documented the base revs that I started my CVS tree from in the initial import/commit message precisely to make it possible to write a script to track changes made in RELENG_4. I probably am not going to merge the new RELENG_4 work for several months, but it is definitely part of the plan. I don't expect there to be significant performance differences between DragonFly and RELENG_4 for some time due to the fact that we do not intend to remove the MP lock until it becomes trivial to do so, which will be months away. At some point the fixed VFS layering in DragonFly is going to make it possible to develop VFS-based features that only 5.x has now, but far more generically, and in a userland development environment, and that is the point where the old RELENG_4 will not be able to keep up. My best guess is that that point is a good 6 months away at least. -Matt
