I use ufs so I used tunefs to label all my partitions. tunefs -L ROOTFS /path/to/rootfs and so on for all my ufs partitions. and then for swap, glabel label SWAP /dev/ad1p1 (or your path to swap partition) next mount the root filesystem and edit the fstab. mkdir -p /mnt/rootfs mount /dev/ufs/ROOTFS /mnt/rootfs vi /mnt/rootfs/etc/fstab my fstab looks like /dev/ufs/SSDROOT / ufs rw,noatime 1 1 /dev/ufs/SSDUSR /usr ufs rw,noatime 2 2 /dev/ufs/SSDVAR /var ufs rw,noatime 2 2 /dev/ufs/TMP /tmp ufs rw,noatime 2 2 /dev/label/SWAP none swap sw 0 0 /dev/ufs/SCRATCH /scratch ufs rw,noatime 2 2 but adapt to fit. I then added ahci_load="YES" to /mnt/rootfs/boot/loader.conf and rebooted. as yet I havent tried the rest of the ATA_CAM stuff though. using labels means switching back is easy too (I switched back for a bit until i found the latest smartmon tools supports the ahci ada devices.)
