You should set hostname in /etc/rc.conf. I am mentioning this now because not doing it kept me from running X apps from a DragonFly system on a Windows 10 system with vcxsrv, and I wasted half an hour of my life figuring that out. Apparently this is a lesson I need to keep relearning.

I’ve seen a similar config other places, but it never hurts to note: scrolling in X requires just a few xorg config lines.
If you upgrade DragonFly and one of the shared libraries used by pkg gets updated, you can’t run pkg until you get files, but pkg is the program you use to bring in new files. This chicken-and-egg problem is solved with pkg-static, a version of pkg built without shared libraries.
You may have noticed some format flip-flopping between pkg and pkg-static if you had to run it after the most recent DragonFly upgrade; that is fixed. There’s a larger issue of certificate installation identified there; I don’t know a solution to it, but I do want to mention this for next time pkg breaks for someone – pkg-static will work as backup, including to bring in a new version of pkg.
You’re probably used to the ‘make buildworld; make buildkernel; make installkernel; etc etc’ dance on each upgrade at this point. ‘Tse’ has created a script that rolls that all up into a single action.
In a larger users@ thread about multiple BSD development systems and how to set them up, I spied this tip on making multiple local virtual machines all reachable via SSH.
A question on starting up a virtual kernel on DragonFly and sticking it in the background led to some suggestions – follow the thread.
I am posting this so it can help someone else, someday.
I have a DragonFly-5.4 system. I installed mysql56-server, and started it up. By default, it listens on “*”, which meant it listens on a local socket and IPv6 ::1 – not 127.0.0.1.
2019-06-04 13:35:03 15833 [Note] IPv6 is available.
2019-06-04 13:35:03 15833 [Warning] Failed to reset IPV6_V6ONLY flag (error: 45). The server will listen to IPv6 addresses only.
I put bind_address=127.0.0.1 into my.cnf to get IPv4 loopback to work. Local socket connections still worked either way. I’m not using IPv6 on this machine, so this solution works in this situation. I’m not sure my mysql decides to go only IPv6 based on a strange flag, but mysql is reliably unreliable.
Remember the commit that autocreates human-readable disk device names under /dev? (Here’s a reminder.) It’s now in 5.4 – technically, since 5.4.2. Anyway, it will automatically identify the root USB disk when you boot from a USB .img file, so you no longer have to guess which /dev/daX file it was – usually da8 but sometimes you got a surprise instead.
