I have a running installation on a 20 GB disk I'd like to move to something a little bigger and then take advantage of the new space.  Is that something I could do with DD and then use another program to expand my filesystems into the available space?  What would I use to expand the filesystem and is it available from the command line or by using knoppix, etc.?

Power off
Install second drive
Boot finnix
mkfs new partition(s) on new drive
mount /dev/<oldpartitioni>/ /mnt/oldmount
mount /dev/<newpartitioni>/ /mnt/newtarget
rsync -plarv /mnt/oldmount/ /mnt/newtarget/
mkswap /dev/secondrive
vi /mnt/newtarget/fstab (fix hda <-> sda changes)
vi /mnt/boot/grub/menu.lst (fix hda <-> sda changes)
grub --no-floppy
  root (hd1,0)
  setup (hd1)
  quit
poweroff
yank old drive
power on


dd takes too long, and isn't too kind to resizing partitions
