Definitely go into single user mode first (telint 1).  You don't want
processes writing to log files, spool files, etc... while you do the
migration.  When you're finished, your new partition should be mounted
as "/var /dev/sda?" or programs will certainly complain.

  1.  Go Single User
  2.  mount -t <ext2> /mnt /dev/sdaX
  3.  Copy files via your favorite method ("cp -a /var /mnt" should work).
  4.  umount /mnt
  5.  umount /var
  6.  Edit fstab to point /var at /dev/sdaX
  7.  mount /var (now on the new disk)
  8.  exit (go back to multi-user mode)
When moving partitions it's important to use a method that preserves
permissions.  Otherwise all hell can break loose... When your
comfortable with the transfer, reclaim the original /var for some other
