Hello docmasters,
I added answers to the two most (un-)popular questions on the ccd list.
Please review and commit at your leisure (or I'll do it if they're ok).
Thanks
Satoshi

+ <heading>What's inappropriate about my ccd?</heading>
+ <p>
+ The symptom of this is:
+ <verb>
+ host# ccdconfig -C
+ ccdconfig: ioctl (CCDIOCSET): /dev/ccd0c: Inappropriate file type or format
+ host#
+ </verb>
+
+ <p>
+ This usually happens when you are trying to concatenate the
+ `c' partitions, which default to type `unused'. The ccd
+ driver requires the underlying partition type to be
+ FS_BSDFFS. Edit the disklabel of the disks you are trying
+ to concatenate and change the types of partitions to
+ `4.2BSD'.

+ <sect1>
+ <heading>Why can't I edit the disklabel on my ccd?</heading>
+ <p>
+ The symptom of this is:
+ <verb>
+ host# disklabel ccd0
+ (it prints something sensible here, so let's try to edit it)
+ host# disklabel -e ccd0
+ (edit, save, quit)
+ disklabel: ioctl DIOCWDINFO: No disk label on disk;
+ use "disklabel -r" to install initial label
+ host#
+ </verb>
+
+ <p>
+ This is because the disklabel returned by ccd is actually a
+ `fake' one that is not really on the disk. You can solve
+ this problem by writing it back explicitly, as in:
+ <verb>
+ host# disklabel ccd0 > /tmp/disklabel.tmp
+ host# disklabel -Rr ccd0 /tmp/disklabel.tmp
+ host# disklabel -e ccd0
+ (this will work now)
+ </verb>
