Matt Dillon is starting work on cache_lookup(), for at least the next week or so. When implemented, it should lead to some very interesting changes in the filesystem. This may be backportable to FreeBSD, too. Quoted text follows:

DragonFly BSD must be a legitimate operating system now. Tobias Florek has come up with a way to purchase a plush Fred mascot. No sales info yet…

Joerg Sonnenberger posted a long writeup of possible directions for a packaging system. I’m repasting it verbatim, as there’s no need to sum up yet.

No major events, but a few small items over the weekend and U.S. holiday:

– Hiten Pandya suggested creating downloadable patchsets for unstable items like ACPI that come from other operating systems, so that people can try them without placing unstable code into the default Dragonfly setup.

– Lots and lots of talk about sysinstall; nothing was really resolved other than that language preferences polarize discussion. Matt Dillon pointed out he was more interested in figuring out RCNG integration, in any case.

– If you, like me, aren’t familiar with RCNG, Jeremy Messenger posted these links (all about the NetBSD version, but that’s close) for more info:

– Serial console support doesn’t seem to be working, though the settings should be the same as with FreeBSD-stable.

– I “announced” this web page, and nobody said anything bad. Yay!

Matt Dillon summarized what he’s been thinking so far for the system installation process:

(Quoted directly from his post)

* Make CDRom #1 a fully live image, allowing the system to boot into a
complete environment. Include various additional tools on the CDRom,
including X.

* Split a normal installation into two stages. Stage 1 is responsible
for FDISK and basic partitioning (/, swap, and /usr), and simply copies
the CDRom to the hard drive and reboots. Stage 2 is responsible for
the more sophisticated aspects of the installation. Both stages
will use the same scripts, languages, & utilities and such to do
their work since both the CDRom boot and the HD boot will have a full
environment to play in.

* Choose a set of tools to build the installation GUI. Desired features
are to be able to run the installation from a character terminal, from
a graphical environment, from a serial port, from a remote
character terminal or graphical environment via the network, or
totally automated.

What I am currently proposing:

* Place Apache, PHP4, lynx, and some sort of browser (if we can get it to
fit) on the live CD.

* Use Apache and PHP4 as the backend to the installer, lynx as the
character terminal frontend, or a browser as the graphical frontend.
The installation code would be written primarily in PHP4.

* The PHP4 code could make use of a simple database and the existing
RCNG scripts to hold onto persistent data and execute its various
functions.

The daily snapshots mentioned earlier at http://chlamydia.fs.ei.tum.de/ were garbled if you downloaded them via the web before today. (FTP downloads worked dandy.) It’s now fixed.

Robert Garret is working on a new system installation method. The consensus so far seems to be that the installation CD should be a “live CD”, meaning that it boots and runs a full system, whether or not it can see the installation system’s hard drive.

He’s also decoupling the start of installation – booting, partitioning, base system, etc. – from the third-party software installation, which will be nice for anyone who’s endured complete reinstallations because something in the XFree86 setup process got all mangled. My personal record is 4 reinstalls.

leaf.dragonflybsd.org is now available for developers via SSH.

Also, a number of folks have reported success running DragonFly BSD under
VMWare, Bochs, and qemu (with modifications).

Following is a list of the shell access requirements from Matt Dillon.

Simon ‘corecode’ Schubert has a machine set up to build snapshots on a daily basis, at:

http://chlamydia.fs.ei.tum.de/

( pub/DragonFlyBSD/snapshots/i386/ is where you’ll want to go, probably.)

What a euphonious name… New builds will probably finish around 11 AM (GMT+2), which is 4 AM for me in New York, and 1 AM if you are on the Left Coast of the US.

There’s a new documentation newsgroup/mailing list (each posts to the other) for documentation. Check the Forums page for information on all the lists. Hiten Pandya appears to be the instigator.

Matt Dillon’s work diary is updated, too.

Apparently all the old-style prototypes using __P are now gone. Robert Garret is the one to thank for removing the thousands of entries.

Matt Dillon has brought in his slab allocator. This handles memory allocation, and is almost nearly multiprocessor-safe, meaning no fancy locking will (eventually) be required for memory allocation.

I may be wrong, but this sounds like a partial fix to the issue of the “Giant Lock” from FreeBSD 4. Matt Dillon’s description follows…

The inital installation process for DragonFly BSD was to install FreeBSD 4.8, import the DragonFly BSD code from CVS, and then build over that system. Relatively time-consuming, especially when hitting the mergemaster step. Now, thanks to the efforts of David Rhodus, you can nab the first installation image.

It’s just over 150M.
