I have been > unable to figure out how to do this on FreeBSD.) To have a FreeBSD equivalent to linux UUID partition identifiers in /etc/fstab, set a label for a partition (gpart for GPT, glabel for MBR), `X` is the partition number as reported by `gpart show`. gpart modify -i X -l <label> ada0 glabel label <label> da1s1a Then in the /etc/fstab you can use something like ('rootfs', 'home' and 'swap' being the actual labels assigned to the partitions): /dev/label/rootfs / ufs rw 1 1 /dev/label/home /home ufs rw 2 2 /dev/label/swap none swap sw 0 0 And this would work no matter how and where you connect the disk. Also, the FreeBSD bootloader knows to detect different installs (e.g. multiple FreeBSDs, say release, current and stable) on the same disk only if the disk is MBR partitioned.
