OverTRIMmed

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 …

virtio_random in DragonFly

Something I didn’t know existed but makes sense now that I do: a virtualized randomness device, added to DragonFly.  Entropy is usually provided through hardware, so of course you’d need something for it in a VM.

BSDNow 265: Software Disenchantment

BSDNow 265 has a con report – the just-finished EuroBSDCon 2018 in Romania, plus the usual roundup of news items.  One news item that will be useful someday: how to perform a BIOS update on a non-Windows computer.

Dumpoffon

If your kernel panics, the current state of memory can show why.  That memory dump needs to be saved somewhere.  ‘dumpon’ is the command to specify the device that will keep it.  If you want to turn it off, you end up using the odd syntax ‘dumpon off’.  Thanks to Aaron Li, there’s now a …

Hyper-V and DragonFly

I tried Hyper-V, and of course, I had to install a virtual DragonFly system.  Sascha Wildner very helpfully pointed out that DragonFly on Hyper-V requires a legacy network adapter and a gen-1 image type; both changes you can make during initial setup.  I’m noting it here for the benefit of future people walking down the …
