DragonFly BSD users will be happy to learn the operating system's HAMMER2 file system has received a number of improvements. The fle system can now better recover from crashes and offers the ability to have an encrypted root volume. "Matthew Dillon's been working on 'reliable on-media topology' for HAMMER2. If you had a crash at just the right time with HAMMER2, you wouldn't lose data but you might have to do some manual cleanup. (Don't ask me the steps; never happened to me.) With these changes, that doesn't happen any more. It's present now in -master and will be in what should be DragonFly 5.4.1 by the end of the year. He has a post to users@ that goes into better detail. If you want way too much detail, you can check the commits." More information and links to in-depth details on the changes can be found in a DragonFly BSD Digest post.
