SEMIBUG is meeting online tomorrow, the 21st. The Emacs presentation that was originally scheduled has been postponed to October 19; it’ll be lightning talks instead.
Update: postponed to next week.
The recent tmux package update reminds me to mention ‘pkg lock’. When you update packages, pkg will update everything. If there’s a package you don’t want changed, the pkg lock(8) command will keep it at the current version. There can be some other packages held back because of dependencies, but that’s OK. Don’t forget to pkg unlock when no longer needed…
NYCBUG’s hosting “Extreme scripting with KSH and AWK” with G Clifford Williams, tomorrow. It’s online, so everyone can get the lesson.
If you want to update to the now fixed tmux port, you’ll want to add a -f to the pkg command to force it; the version number hasn’t changed.
tuxillo has built a new set of packages for dports; upgrade using the instructions in his post. (Though ‘pkg upgrade’ has generally worked for me as the quickest solution.)
I didn’t realize this, but there was a bounty offer for porting a hypervisor to DragonFly, listed on the DragonFly Code Bounties page. Aaron LI did it, and now he’s promptly paid, too. Put your name on a bounty if you’re willing and interested in paying.
Aaron LI posted a summary of how he went from zero to done, so to speak, porting NVMM to DragonFly. There’s some interesting future projects there, too.
The headline says almost everything, in this case. There’s a HOWTO for DragonFly NVMM which should get most of what you want to do, and I’m sure it will be updated.
Here’s something I just learned: If you are running dma(8), /etc/dma.conf will contain MAILNAME. If your email server is somewhere else, but you set MAILNAME as your domain – dma will deliver locally.
I had /etc/dma.conf set with MAILNAME shiningsilence.com – so dma kept delivering overnight periodic results to root, which was aliased to justin@shiningsilence.com in /etc/mail/aliases and so it was delivered to ‘justin’ locally on the machine.
Changing MAILNAME to www.shiningsilence.com – the host you are reading right now – fixed the problem. Now, whether this was an automatically set config or something I misconfigured some years ago… I can’t tell.
Aaron LI’s added NVMM, hardware acceleration for virtual machines, to DragonFly.
The version of qemu in dports is not set up to support this, yet. Until then, you can download a prebuilt version.
Since NVMM originated on NetBSD, the NetBSD documentation page for it describes how to use it quite well. There’s a man page in DragonFly for it too, of course. There’s even basic machines to try.
ChiBUG meeting is at 6 PM at the normal place, which means you should go if you are near, and vaccinated.
Many, many times over the years I have tried answering problems with “… and maybe something’s wrong with the RAM?”, which is always possible but not always probable. For once, it’s really what happened in this story of strange HAMMER2 errors.
This note from James Cook describes how to get Wireguard functioning on DragonFly; his linked patch is not necessary at this point since it’s been committed to dports – though not in the latest binaries.
Nelson H. F. Beebe posted links to two ACM articles; one about SSDs and the other about filesystem resilience. Matthew Dillon chimed in with his thoughts specifically on HAMMER2.
I’m actually some days late in reporting this, but there’s a new full build of packages for DragonFly 6.0; it’s following the quarterly release schedule for ports, so 2021Q2 is the base.
This goes with the recent merges from -current into 6.0. Now is a good time to update your system completely, if you have not already.
You may run into a setup issue with Wireguard when trying to set it up on DragonFly. Keep an eye on this Go bug report if so.
Update: here’s a solution in the works.
This query had karu.pruun write a short note on how to contribute (device driver) development work to DragonFly. Don’t forget grok.
James Cook continues to work on zalloc, and he’s published a small report on his progress.
James Cook is interested in working on zalloc in DragonFly, taken from the projects page. Follow his questions and the answers if this interests you.
