>Description:
	Since upgrading to RELENG_6_2, I can't mount CDs anymore. I get:
	"mount_cd9660: /dev/acd0: No such file or directory"
	Using "mount -t cd9660" (below) doesn't even access the CD-ROM device
	unlike "mount -t ufs", which actually reads the CD to find out that the
	CD-ROM hasn't got a UFS super block.
	If you have instructions for me, how I could support more useful information,
	please tell me.
>How-To-Repeat:
	root:~> ls -ld /dev/acd0 /mnt/cd
	crw-r-----  1 root  operator    0,  60 May 28 16:57 /dev/acd0
	drwxr-xr-x  2 root  operator       512 May 24 01:32 /mnt/cd
	root:~> mount -rt cd9660 /dev/acd0 /mnt/cd
	mount_cd9660: /dev/acd0: No such file or directory
	root:~> mount -rt ufs /dev/acd0 /mnt/cd
	mount: /dev/acd0 on /mnt/cd: incorrect super block
	root:~> dd if=/dev/acd0 of=image bs=2048
