This isn't new (to me). Having ufs-labelled md-devices brings me those 
messages since 6.x (since in use geom labels), because the mdconfig 
rc-scripts don't know about "/dev/md0 == /dev/ufs/FOO" and therefore mount 
the md-devices directly instead of the labels which makes the labels
disappear directly after mdconfig has just "created" them.

How would one get the ids of ufsid-labels when hidden? glabel list shows
only the "active" labels, especially doesn't show the ufsid-label if the
device is mounted by its "legacy" devicename (just tried that). dmesg  
seems the only source of information for that so far.

PS: In gerneral I find it very useful to operate on labels instead of 
"legacy" device names, especially for S-SATA disks. I even use 
/dev/ufs/ROOT instead of /dev/ad<random>s1a which works perfectly:

# dmesg | grep ROOT
GEOM_LABEL: Label for provider ad6s1a is ufs/ROOT.
Trying to mount root from ufs:/dev/ufs/ROOT
