DragonFlyBSD’s HAMMER2 file-system seeing new improvements

DragonFlyBSD lead developer Matthew Dillon has recently been working on further refinements to HAMMER2 for the next DragonFlyBSD operating system release.

The latest HAMMER2 activity in the past few days has included improving its CPU performance and adding a new hammer2 recover" directive. The HAMMER2 recover support allows for recovering/undoing single files as well as preliminary support to recover entire directory structures.

DragonFlyBSD always feels like the one nobody talks about or uses, with FreeBSD, OpenBSD and NetBSD taking the spotlight instead. Are any of you folks using it? How has it been?
