Sometimes I'm confusing them, because I usually don't use the
installer and usually use fdisk (if needed), bsdlabel and
newfs. :-)

Maybe the required device driver is not part of the 8.x
GENERIC kernel? So for example a drive could come up either
as /dev/ada0 or as /dev/ad6, depending on how the recognition
order and PATA / SATA thing is handled by the system and
its BIOS. Labels will work independently from wheather
the device will be recognized as ATA disk (for example
/dev/ad6s1a being the root disk) or SATA disk (where
/dev/ada6s1 would be the root disk).
