DragonFly BSD 2.2 Released

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!

Re:First

I don't think so, Mr. Shuttleworth...

Re:First

[Anonymous Coward]

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.

Re:First

FreeBSD is practically the same code as 386BSD. DragonflyBSD is practically the same code as FreeBSD.

Hence DragonflyBSD is the same as 386BSD.

[BOFHelsinki]

Not by a long shot. All three kernels are vastly different.

Re:First

[arogier]

horrendously different.

Good to see

[MichaelSmith]

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

Re:Good to see

[auric_dude]

Lots of BSD http://daemonforums.org/index.php and a few BSD liveCD http://daemonforums.org/showthread.php?t=1505 to try before you buy.

Slashdotted :)

[CannonballHead]

Hmmm, 4 posts and it's slashdotted? I hope their server isn't running on BSD, for the sake of its publicity :)

Re:Slashdotted :)

[portscan]

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.)

Re:Slashdotted :)

[Tubal-Cain]

don't you think that all the people downloading ISOs might have something to do with it?

Most people that can are probably torrenting.

Where have you been?

[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.

Re:Where have you been?

[Predius]

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

Re:Where have you been?

[MichaelSmith]

OS X is a kludge.

Re:Where have you been?

[not already in use]

OS X is a kludge.

Freakin' Word. But it looks pretty.

Re:Where have you been?

[Tubal-Cain]

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.

Re:Where have you been?

[trouser]

What version of Perl are you running?

Re:Where have you been?

[Anonymous Coward]

I wasn't aware Internet ran on MacOSX - I always thought it was mostly Linux and various free *BSD...

The things you learn.

Or maybe the desktop isn't everything.

Release Notes

[SlashdotOgre]

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 ftp://mirrors.isc.org/pub/DragonFly/
TX ftp://mirror.evilprojects.net/pub/DragonFlyBSD/
VA ftp://ftp.theshell.com/pub/DragonFly/iso-images/

And some EU ones:
UK ftp://ftp.as6911.net/pub/DragonFly/
Germany ftp://chlamydia.fs.ei.tum.de/pub/DragonFly/

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

HAMMER Time

[AKAImBatman]

The second release to feature the HAMMER (versioning, among other things) filesystem

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

HAMMER TIME!

Re:HAMMER Time

[fuzzyfuzzyfungus]

But I though that "Stop" errors were a Windows feature...

Re:HAMMER Time

[Anonymous Coward]

No, ufs is too legit to quit.

Re:HAMMER Time

[wisty]

It's a reference to xkcd, right?

Re:xfs sucks

[setagllib]

You'll be fine with ext3 created with largefile4 options, and mounted with data=ordered.

mke2fs -j -T largefile4 /dev/myvg/mylv
