Hi Per,
It seems that on amd64, ccd is included in the RAMDISK and RAMDISK_CD
kernel configuration files :
$ grep ccd /usr/src/sys/arch/amd64/conf/*
/usr/src/sys/arch/amd64/conf/RAMDISK:#pseudo-device ccd 4 #
concatenated disk devices
/usr/src/sys/arch/amd64/conf/RAMDISK_CD:pseudo-device ccd 4 #
concatenated disk devices
/usr/src/sys/arch/amd64/conf/files.amd64:major {ccd = 16}
So that's a good hint that you should be able to use CCD during
install. I'd suggest (as suggested earlier) first installing /var on /
(as it's only ~10MB). Then, when the installer finishes, you can
simply enter your newly installed system with
$ /mnt/usr/sbin/chroot /mnt
After that you can mv /var /var_ORIG && mkdir /var. After that, you
can create a ccd, edit /etc/fstab to mount the new ccd on /var,
temporarily mount it there yourself, move the data from /var_ORIG/ to
/var/, remove /var_ORIG/, unmount /var/, exit the chroot, unmount
other filesystems, reboot and rejoice ;)
Hope that helps,

PS: ccd is included in the default kernel (no matter what platform
you're running). See /usr/src/sys/conf/GENERIC, this is included from
most (all?) platform specific GENERIC's.
