ganz geil!

I am really glad all of my filesystems are under /dev/ufs/ (& swap under /dev/label/). It probably saved me a couple of hours of drunkenly trying to puzzle out why I can't get multiuser. As it is it's been running for three days and I only just noticed.

So there's your lesson, kids! <3 -> devs.
 
I didn't think ada would be enabled by default so soon. Well, it'll be interesting to see if it makes a difference when Phoronix bench it. :)
 
It wasn't there by *default* for me. I had to add options ATA_CAM and device ahci to get it to show up for me.

And actually, this caused a bit of trouble with my UFS label setup. My /home partition is journaled, and the /dev/ufs label for it disappeared with the change to ATA_CAM. I had to edit fstab and revert to ada0p5.journal.

Ah, yeah, my custom kernel appears to have had the stuff added. I remember vaguely hoping that it would work, but I'd utterly forgotten it up till now.
 
Another bit: the addition of "options ATA_CAM" changes /dev/acd0 to /dev/cd0 so I needed to update the "link acd0 cdrom" line in /etc/devfs.conf.

All in all, 8.1 is shaping up pretty well.
