i've never been able to use disklabel with CCD since ages.. I've always
newfs'ed my ccd once the ccdconfig -C done.. i'm using CCD since
FreeBSD 4.x, and a current -stable gave me the same result..

AFAICS, disklabeling CCD is useless. If i need to create more than one CCD,
i create more slice per disk, then CCD them into different disks.

i've tried to, for hours, few years ago when i was a poor student using a
bunch of disk (some old SCSI-1 380mb HD full height) on a FreeBSD 2.x (if
i remember correctly).. Never managed to create more partition on a CCD
slice..

i think so, but since noone were reporting that, i was thinking
that i was doing something wrong while creating those CCDs..
fifi..
