Here is a boot log: It's premature-compatibility-slice-avoidance related. fsck actually honours the devices specified in /etc/fstab. When the root device specified in /etc/fstab doesn't match reality, due to it being the compatibility slice but the kernel having mounted root on a real slice, fsck doesn't know that the specified root device is mounted and doesn't tell the kernel to reload it. This results in the copy in the kernel remaining inconsistent with the disk copy and unclean. mount(8) uses the buggy ROOTSLICE_HUNT hack to hide this problem. Fortunately, mount fails unless forced so the inconsistent state doesn't cause further damage.
