You could also try using Knoppix.
1. Boot up Knoppix.
2. Create the new partition
3. Create the directories on the new partition
mkdir /var, /usr, /home or whatever
4. Copy the mount points off the old disk to the directory on the new
partition using tar
cd /olddisk
tar cf - var | (cd /newdisk; tar xpf -)
5. Remove the mount points on the old disk
rm -fr /olddisk/var
6. Copy the root partition last
cd /olddisk
tar cf - * | (cd /newdisk; tar xpf -)
I have used this method to replace a smaller drive with a bigger drive
several times. The nice thing about using Knoppix is that none of the
files are open when you copy them. Since you are copying partitions,
tar copies the lost+found as well. Be sure to go into the new directory
and remove the lost+found directory.

Thanks, Mike, but that didn't work either. It wanted to take
everything, including all the data from the other mounts, and put it
under /newroot, not just the / contents.

down the whole machine. I created a new ext3 partition of 10G. I

dd if=/dev/oldroot of=/dev/newroot
It worked great except my newroot is 2G, not 10. I tried using
ext2online but there are some incompatibilities, or so it thinks.
Anyone have a suggestion on how I can move my root mount to a new 10G
partition without any catastrophe? Thanks.
The "dd" command didn't copy files, it copied the filesystem,
superblock and all.
Make a new FS on /dev/newroot mount it and use something like
cpio (find / | cpio -pmduv /newroot) to copy the files.
He who laughs last thinks slowest.
