Just mentioning this for archival purposes.

If you are mounting a device as /dev/label/<yourlabel> at boot time, it 
will fail unless you add a ''geom_label_load="YES"'' to your 
/boot/loader.conf file. Had me stumped for a while. This loads the geom 
label module at boot time and so labels are recognized.
