freebsd stable - Jul 2010 - sysistall bsdlabel failure with amd64 FreeBSD-8.1-RC2-amd64-dvd1.iso

Hi stable@,
with amd64 FreeBSD-8.1-RC2-amd64-dvd1.iso
sysinstall failed to correctly repartition a previously partitioned disc.
fdisk however correctly wrote the new slices to the disk,
but sysinstall did not pick up the new slices, so we had to enter fixit
& overwrite beginning of disk with
	dd if=/dev/zero of=/dev/ad0 bs=1024 count=100
PS sysinstall saw /dev/ad0 & /dev/ad0a 

Cheers,
Julian

Were those partitions 'dangerously dedicated' and created by an older
(pre-8.x) sysinstall?
