Probably the biggest new feature of the DragonFly BSD 5.0 release is the introduction of a bootable variant of the next-generation HAMMER2 file system developed specifically for the operating system. Users can finally install DragonFly BSD on a HAMMER2 file system, though it is considered experimental at the moment. When installing DragonFly BSD 5.0 on a HAMMER2 formatted disk drive, the installer will use a UFS formatted /boot partition because, by design, the file system doesn’t immediately free space when deleting or replacing files on the local disk. Also worth mentioning, this release comes with single-image HAMMER2 support.
