Here is the current section 4.2 of Formatting Media For Use With FreeBSD

4.2 Copying the Contents of Disks

Submitted By: Renaud Waldura (<renaud at softway.com>)

To move file[s] from your original base disk to the fresh new one, do:

# mount /dev/ad2 /mnt
# pax -r -w -p e /usr/home /mnt
# umount /mnt
# rm -rf /usr/home/*
# mount /dev/ad2 /usr/home
[end quote]

The problem with this is that pax copies the directory structure of 
/usr/home to /mnt (an ls of /mnt after pax shows usr, of /mnt/usr shows 
home).Thus, once /usr/home is mounted on /dev/ad2, the contents of 
/usr/home will be /usr/home, i.e., the files you want are in 
/usr/home/usr/home.  The correct method replaces line two with

#cd /usr/home
#pax -r -w -p e * /mnt
#cd /

This copies the directories and files from /usr/home to /mnt, but not 
the complete /usr/home directory structure.

CAVEAT: I did not do this on a whole disk.  I added a new disk, sliced 
it, and partitioned the slice, so that I was mounting just a partition 
within a slice, e.g., /dev/ad1s1e.  I used the listed method on /usr, 
and only later discovered that all the files from /usr were now in  
/usr/usr. (I changed /etc/fstab to mount the new slice on /usr, and my 
reboot couldn't go into multiuser mode when all the files supposed to be 
in /usr were not found.)  After fixing /usr, I did a test by creating 
/usr/fred and following the original instructions.  The result was that 
all my files were in /usr/fred/usr/fred.
