I have GEOM_LABEL loaded, but I noticed something strange.
If I boot in single user, I can create and see the labels under /dev/label,  
however if I remount the / filesystem RW then /dev/label disappears.
BUT, if I just replace my / partition in fstab with the seemingly missing  
label (eg /dev/label/rootfs) then the system boots up fine and /dev/label is  
again available to `ls`. Strange stuff, it should be covered in the  
handbook...
Problem solved, I guess.
