I have this in my /etc/fstab: # See /usr/share/examples/fstab/ for more examples. NAME=sb2k5Root/a / ffs rw,log 1 1 NAME=sb2k5Root/b none swap sw,dp 0 0 kernfs /kern kernfs rw ptyfs /dev/pts ptyfs rw procfs /proc procfs rw,nolinux tmpfs /var/shm tmpfs rw,-m1777,-sram%25 /dev/cd0a /cdrom cd9660 ro,noauto The names here are auto-generated from disklabel names, the disklabel says: # /dev/rsd0c: type: unknown disk: ST373207LSUN72G label: sb2k5Root and sb2k5Root/a is the "a" partition on that disk. The kernel attaches wedges via autodiscover (as this machine can't boot directly from gpt) and says: sd0 at scsibus0 target 0 lun 0: <SEAGATE, ST373207LSUN72G, 045A> disk fixed sd0: 70007 MB, 14089 cyl, 24 head, 424 sec, 512 bytes/sect x 143374738 sectors dk0 at sd0: sb2k5Root/a dk0: 93008640 blocks at 0, type: ffs dk1 at sd0: sb2k5Root/b dk1: 50340672 blocks at 93008640, type: swap Should be very similar with direct wedges via gpt (where gpt carries the name internally).
