DragonFly BSD 2.2 Released 44

An anonymous reader writes "DragonFly BSD 2.2 is now available. The second release to feature the HAMMER (versioning, among other things) filesystem — now considered production-ready — it includes 'major stability improvements across the board, new drivers, much better pkgsrc support and integration.' Apart from the CD ISO, this release has a DVD ISO with 'a fully operational X environment,' as well as a bootable USB disk-key image."

    First post to say it's NOT dead!

      Yes but looking at the number of comments for a front page slashdot story: wow, no one really cares.

      To be honest, it's surprising. It seems like they are doing a lot of interesting things, and it's a usable system, not just purely experimental.

      Elegy For *BSD

      I am a *BSD user
      and I try hard to be brave
      That is a tall order
      *BSD's foot is in the grave.

      I tap at my toy keyboard
      and whistle a happy tune
      but keeping happy's so hard,
      *BSD died so soon.

      Each day I wake and softly sob
      Nightfall finds me crying
      Not only am I a zit faced slob
      but *BSD is dying.

      BSD isn't dead, BSD is dying. There's a difference.

    ...that somebody in BSD land is doing something genuinely different, and making it work.
    • by Anonymous Coward

      Someone in BSD land already DID do something different and something that works. In fact, it is so different, and works so well that it is now the most popular version of Unix ever made, eclipsing every other version of BSD and Linux by many orders of magnitude. It is used by anyone who has work to do and is sick of the hassles of the "open sores" development model and the unreliability of Windows.

      It's called "OS X", and it is made by Apple.

        OS X (Which I love as a workstation) isn't doing BSD any favors... they still don't have threading right...

        OS X is a kludge.

        OSX benefits from a foundation of Open Source software and a userland developed with a centralized control that holds the developer's paychecks.
        The scratch-an-itch method of development works great for the kernel, but can get a little messy in the GUI.
        That is one reason I think MS could survive doing the same thing Apple did with OSX.

    Hmmm, 4 posts and it's slashdotted? I hope their server isn't running on BSD, for the sake of its publicity :)
    • hardly slashdotted. don't you think that all the people downloading ISOs might have something to do with it?

      And of course it's running BSD (Netcraft [] confirms it.)

        Most people that can are probably torrenting.

    I was able to get in before it was fully slashdotted (it was crawling when there were only two posts here).

    Here are some US mirrors:
    CA []
    TX []
    VA []

    And some EU ones:

    Here's the Release Notes:
    Release Improvements

    * A new DVD ISO release image is now available, in addition to the CD release.
    * The new DVD release has a full X environment ready-to-go and many packages pre-installed.
    * A full pkgsrc tar is now available on the CD/DVD in /usr.
    * Full sources tar now available on the DVD (kernel sources only on the CD), in /usr.
    * The nrelease build now trivializes package selection for people creating customized releases.
    * The installer is now able to create a HAMMER filesystem setup.

    Kernel changes

    * First step towards AMD64 support (done by Jordan Gordeev during the Google Summer of Code 2008).
    * The system control intr_mpsafe is enabled by default.
    * Move /kernel to /boot/kernel and /modules to /boot/modules.
    * Add RFC3542 support (done by Dashu Huang during the Google Summer of Code 2008).
    * Add HW checksum support to the loopback interface, which doubles performance.
    * acpi_cpu(4) update. It's now possible to use higher (lower power usage) C states than C1 in modern (multicore) CPUs.
    * First steps to use network threads without the Big Giant Lock (this feature is considered experimental).
    * Fixed CVE-2008-2476 IPv6 security issue with modified patches from NetBSD.
    * bridge_input works now in parallel.
    * Fix bugs in dealing with low-memory situations when the system has run out of swap or has no swap.
    * Major rewrite of usched_bsd4 and related support logic, plus additional improvements to the LWKT scheduler.
    * Major revamping of the pageout and low-memory handling code.
    * suser_* replaced with priv_* implementation from FreeBSD.

    HAMMER changes

    * HAMMER is now considered production-capable. Many bug fixes and other improvements have been made.
    * It is now possible to boot from a HAMMER-only disk. No need for a single UFS partition for /boot. However, for production systems we still recommend a small UFS /boot followed by swap followed by one large HAMMER partition.
    * Add HAMMER read support to the boot loader.
    * Now uses per-mount kmalloc pools for bulk data structures, particularly for inodes and records.

    Hardware changes

    * Add ACPI support module for IBM/Lenovo Thinkpad laptops (from FreeBSD).
    * Add ACPI support module Asus laptops (from FreeBSD).
    * Add acpi_video(4) - a driver for ACPI video extensions (from FreeBSD).
    * It is possible to power down PCI devices during

    So what you're saying is that efs2 and ffs/ufs can't touch this.
