 I am noting that the ccd1 will not keep fstype, fsize, bsize, and cpg when
 I set them to "4.2BSD     1024  8192    16".  Interesting, but since newfs
 works, I am going to ignore this probably unimportant tidbit.
 
 OK, stupid question back to you.  What do you mean partition sizes are
 multiples of the ccd interleave?  I believe the answer is yes, with double
 the number of twos in factoring.

 ccdconfig -g
     ccd1            16      8       /dev/sd7g /dev/sd9g /dev/sd12g /dev/sd14g
 ------------------------------------------------------------------------------
 /etc/ccd.conf looks like:
     ccd1    16      none    /dev/sd7g /dev/sd9g /dev/sd12g /dev/sd14g
 ------------------------------------------------------------------------------
 The four disks look like this (verified the same via diff):
     # /dev/rsd7c:
     flags:
     bytes/sector: 512       sectors/track: 575      tracks/cylinder: 32
     sectors/cylinder: 18400 cylinders: 483          total sectors: 8887200
     rpm: 10000              interleave: 1           16 partitions:
     #        size   offset    fstype   [fsize bsize   cpg]
       c:  8887200        0    unused        0     0         # (Cyl.    0 - 482)
       g:  8868800    18400    4.2BSD     1024  8192    16   # (Cyl.    1 - 482)
 ------------------------------------------------------------------------------
 And the ccd1 disklabel:
     # /dev/rccd1c:
     type: ccd               disk: ccd       label: default label    flags:
     bytes/sector: 512       sectors/track: 575      tracks/cylinder: 32
     sectors/cylinder: 18400 cylinders: 1928         total sectors: 35475200
     rpm: 10000              interleave: 1           16 partitions:
     #        size   offset    fstype   [fsize bsize   cpg]
       c: 35475200        0    unused        0     0         # (Cyl.    0 - 1927)
 ------------------------------------------------------------------------------
 ccd1:       /usr/games/factor 35475200
             35475200: 2 2 2 2 2 2 2 2 5 5 23 241
 sd7:        /usr/games/factor 8868800
             8868800:  2 2 2 2 2 2 5 5 23 241
 interleave: /usr/games/factor 16
             16:       2 2 2 2
 ------------------------------------------------------------------------------
 
 I am going to re-run the test with just 2 disks in the ccd. (make the test
 as simple as possible...)
