Chris Turner is looking to implement something similar to OpenBSD's mount_vnd(8) operation, where virtual disks can be mounted at boot.  He talks about some of the work and ideas at length.  If you don't feel like reading about it, you can instead mess with it; he has a tarball of the current state of his work linked in his message.
If you're running the bleeding edge version of DragonFly, because Sepherosa Ziehau's recent work makes it possible to boot systems that were previously bootable, you may need this sysctl trick loader tunable in loader.conf: debug.acpi.enabled="pci pci_link" How will you know that you need it?  The system will run strangely slow.  The command enables ACPI interrupt routing, which corrects for mptable problems.
pf in DragonFly 2.9 is currently equivalent to OpenBSD's 4.4 version. This is probably what will be in the next release version of DragonFly, as Jan Lentfer, the man responsible for the rapid, recent pf upgrades, is a new father (again). Congratulations on the new daughter, Jan!
Summer of Code 2011 student applications can be made now.  If you're a student, you've got until April 8th to get it done!  (Calendar)  Remember, you can't be too organized, too early.
John Marino's work on getting support for DragonFly 'natively' into binutils, upstream, has been successful.  Thanks, John!
I've found enough good links I'm able to schedule this post ahead of time.  Yay!
Sascha Wildner has added in binutils version 2.21, replacing 2.20.  Note that both 2.20 and 2.21 are 'optional', so you have to set BINUTILSVER to use them.  Otherwise the system defaults to the also-installed binutils 2.17.
The mentor signup page for Google Summer of Code 2011 as of this writing still says "We have temporarily disabled the creation of new requests and invites in preparation of the launch of the new UI for Melange later this week.", as it has said since the 20th. So, if you're wanting to mentor, keep an eye on it.  I'll send mentor requests to any of the names on my list of people that have already expressed interest, if I get to a working version of the page before you do...
As already mentioned on this Digest, the freeze for the next quarterly release of pkgsrc, pkgsrc-2011Q1, has started.  I've also completed several bulk builds of pkgsrc-2010Q4 and pkgsrc-current using DragonFly system with GCC 4.4.  Francois Tigeot has very kindly gone out of his way to get some of the (relatively few) broken packages listed in those builds to be fixed.
This is the BSD-licensed version of libiberty, which was removed because it didn't ever actually make it to being a replacement.
As noted in announcements, pkgsrc is entering a 10-day freeze period starting tomorrow.  If everything goes to plan, the next quarterly release of pkgsrc, 2011Q1, will be released April 3rd.
My first bulk build of pkgsrc with gcc 4.4 has completed; the results are available.   Notice that most of the errors are from checksum problems with downloads, not actual problems from the compiler change.  I'm starting a new build to see if the checksum problems go away with fresh downloads.
