The reason there's not a lot of documentation about upgrading FreeBSD-arm in-place is simply that it's exactly the same as i386 or amd64. All the existing documentation applies exactly. There are a few minor bits of trivia: * It takes a while: allow 15 hours on an RPI2, 40 hours on a BeagleBone Black. * Crochet normally sets the KERNCONF in /etc/sys.mk so you should not need to set it manually. * If you want to tweak the kernel configuration, it's in the usual place: /usr/src/sys/<platform>/conf/<config> * 1GB RAM is not enough for buildworld, so you'll need to configure swap space. I normally aim for ram + swap >= 1.5GB, so at least 512MB on an RPI2. * You also need to make sure you have enough disk space: I think I've successfully done a full buildworld with an 8GB SD card. 16GB is ample. > >> Also, powerd definitely works on RPI2.
