That somewhat symmetric title is to note a new device feature on DragonFly: if you use disklabel to label a disk, its parts will automatically appear under /dev. So, if you label a disk MYVOLUME, and it has 3 parts, a, b, and d, you will automatically gain a /dev/part-by-label/MYVOLUME.a, /dev/part-by-label/MYVOLUME.b, and a /dev/part-by-label/MYVOLUME.d.
If you were having trouble booting a DragonFly installer – or rather, you could boot but never find a disk to install on, this commit adding support for Sunrise Point, Lewisburg, Union Point, and Cavium ThunderX chipsets may fix your issue.
Two links I yoinked from conversation in EFNet #dragonflybsd: there’s a “powersave” power management page on dragonflybsd.org that for some reason wasn’t linked in the main documentation page. I fixed that, and you may want to look at it and change your mwait settings, or look at the corepower(4) module. (From ivadasz’s comments; thanks!)
There’s also an older page on DragonFly and grub2 that may be interesting to anyone looking to boot. (From aly’s comments; thanks!)
An oddly uplifting batch of BSD stories this week.
- Tor on OpenBSD, part 5 and part 6.
- Slides and transcript and code from the November NYCBUG meeting. (I wish all BUG meetings had this.)
- MeatBSD, the December SEMIBUG meeting, is a meetup at a local meat-heavy restaurant, December 18th. Plan for it now, cause you need to reserve a seat.
- Steam Autumn Sale Highlights for OpenBSD.
- OPNsense 18.7.8 released.
- GhostBSD 18.10 Now Available. (via)
- Abandon Linux – Move to FreeBSD or Illumos. A pro-ZFS item, which means plenty of filesystem comments at the source link. (via)
- Debugging rcctl in OpenBSD. (via)
- FreeBSD for Thanksgiving. This is a nice story to hear. (via)
- Stardew Valley on FreeBSD. (via)
- Cheap BSD-friendly notebook? Thinkpads thinkpads stinkpads thinkpads. (via)
Did you use the digi(4), rp(4) and si(4) serial device drivers in DragonFly? I don’t think so, but you definitely can’t now.
Matthew Dillon recently fixed a TRIM bug, where a TRIM command was being issued unconditionally, regardless of the mount flag, and duplicating the action if it was set normally. It’s fixed now. This would only have any significant slowdown on UFS, which means it would only affect installworld – the rest of your mounted volumes are HAMMER, right?
BSDNow 264 is available now and has the usual roundup of news, including discussion of Threadripper performance that I’ve avoided.
For anyone considering the purchase of a Ryzen system given the good benchmarks/power usage, here’s some discussion on users@ about which model is which.
I’ve been linking to other parts of this, but now it’s on one page: “Zenripper“, talking about how to overclock/underclock a Threadripper system on DragonFly.
