David Leimbach noted that Ron Minnich was porting Plan 9 namespaces to FreeBSD, which duplicates some of the security features to be covered by VFS. Ron Minnich’s web page has more data on this and other technologies.
Hiten Pandya (email@example.com) is looking for anyone using a AMI MegaRAID card, who is willing to test a patch for FreeBSD-4/DragonFly.
dfports/emulators/vmware2 is in, though Matt Dillon warns that it is not yet functional.
File System Exerciser, in
tools/regression/fsx, has been added, by David Rhodus.
fdisk now has a -p option, to let it operate on disk images.
David Rhodus has fixed the problems reported by Richard Sharpe where Linux NFS clients couldn’t achieve above 5 MBps throughput.
I wrote down the explicit steps I used to get a DragonFly machine running and up-to-date; I’m including them here for the benefit of others. This was working as of mid-September.
** Updated December 2003; silly typos.
** Update February 2004: This guide was written using FreeBSD 4.8 as a guide; it may break. There is a guide page on dragonflybsd.org that talks about upgrading from FreeBSD 4.9.

Kip Macy listed a number of tasks left for his checkpoint/restart work, not all of which he will be covering. If this sounds interesting to you, jump in!

In part of a conversation about checkpoint work, Matt Dillon described the preferred process for code changes. I’m pasting it in, wholesale.

Paul Jarc brought up “>Slashpackage as a possible solution to the ports system on DragonFly; Mike Porter pointed out that it covers most everything except shared library handling.
Emiel Kollof is working on the NVIDIA binary video driver; so far it loads correctly, but doesn’t work in X11.
In other discussion about a microkernel, Gary Thorpe noted these historical links about softupdates:
And Pedro Guffuni followed up with this:
Joshua Coombs noted he would like to work on a new firewall strategy for DragonFly, and pasted in some of his notes. They are complex enough that it’s better to paste than to sum up. (I sure could use the multiple routes he talks about.)
Pasted material follows:

It looks like the PC Card problems mentioned earlier are really a problem with the DHCP client. David Rhodus is looking for someone to try a new import of the ISC DHCP code. (Updated – an import from FreeBSD-5 is happening instead, since that fixes some problems with the most recent ISC code.)
Galen Sampson found that using NFS without -maproot will cause file truncation; Matt Dillon has a temporary hack that will fix it, which will be committed by the end of the week if it works without trouble.
Matt Dillon disabled background bitmap writes, as it can apparently cause certain race conditions. He notes: “Eventually the problem background bitmap writes solved will be solved more generally by implementing page COWing durign [sic] device I/O to avoid stalls on pages undergoing write I/O.”
Emiel Kollof found that to get a PCMCIA network card going, you need to add these lines to /etc/rc.conf: (replace x’s with your static address, if applicable.)
pccard_ifconfig="inet xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxx"
John De Boskey posted he had variant symlinks working under FreeBSD 4-Stable, and notes these patches:
And this post to freebsd-stable.
During a separate thread about microkernels (short summary: it ain’t happening), Pedro Guffuni pointed out Exokernel, a OS project where most everything was in libraries.
