part-by-label: an additional benefit

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.

Power notes, booting notes

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!)
