 * The downside of this is that if you already have a ccd set up on your
 * machine, it will stop working when you recompile the kernel from the
 * latest sources.  To avoid this, you should either (1) change the
 * disklabel to move the partitions 16 sectors towards the beginning of
 * the disk, or (2) change the definition of CCD_OFFSET to 0 in
 * sys/dev/ccd/ccd.c.  Or just back up, recompile, and restore.

Per Paul-Henning's request, I added an #ifndef-#else around the
CCD_OFFSET so you can do a

options "CCD_OFFSET=0"

(double-quotes mandatory) in your kernel config file if you don't want 
to modify the source and still keep the old ccd volumes.
