0. Insert disk into machine.
1. Make a partition on the new disk (cfdisk/fdisk).
2. Make a filesystem on the new disk (mke2fs) 
3. Go into single-user mode and shut down as many daemons as you can
find.  Make sure there are only the very basic processes running.
4. Mount the new disk somewhere like /mnt
5. Copy everything from /var/ to /mnt/.  You can use tar for this but if
you use 'cp -dpR' it does just as good a job.
6. Edit /etc/fstab so that it will mount /var from the new disk.
7. Delete everything under /var.
8. Reboot or bring the machine back to normal manually (I recommend
rebooting).

I've done this a few times before without any problems and I'm pretty
sure the above is what I did.  It's pretty simple assuming you know how
everything works so if you don't, now would be a good time to ask. :-)
