A few checks later: it seems that my problem isn't related to bsdlabel. I scpied images generated (dd+bsdlabel) on 7.2 to the 8.1 host, and vice versa. It seems that when I mdconfig -a -f $file the 7.2 img on the 8.1 host, /dev/md${x}c doesn't appear. But when I add the 8.1 image on the 7.2 host, /dev/md${x}c is correctly added. What is happening?!
