BSD and Darwin derivatives

DragonFlyBSD 5.0 is the first release with preliminary boot support for HAMMER2, the project's new filesystem.

Preliminary HAMMER2 support has been released into the wild as-of the 5.0 release. This support is considered EXPERIMENTAL and should generally not yet be used for production machines and important data. The boot loader will support both UFS and HAMMER2 /boot. The installer will still use a UFS /boot even for a HAMMER2 installation because the /boot partition is typically very small and HAMMER2, like HAMMER1, does not instantly free space when files are deleted or replaced.

HAMMER2 looks like it is an interesting alternative for ZFS / btrfs. Compression, deduplication, low memory footprint, even possible to use it in a cluster.
