Would be nice. I've resized a few ext2 partitions, but haven't found any 
way to move the front of the partion, short of nuking the partition 
completely and restoring from a backup.

If you've got enough free space on the drive, you could set up a 
temporary partition elsewhere and just copy all of the stuff. I've done 
this a couple times when I've decided to resize partitions on my laptop 
while commuting to school. (Resizing partitions while commuting is 
living dangerously, but I know that my documents are safely in 
Subversion if anything goes wrong, and I know that I can always find a 
CD and start from scratch when I reach school if something goes wrong.)

Only if you take my "move stuff to another partition" strategy.

I use
$ aptitude search -F '%100p' '~i!~M' > thefile
to backup my package list

I've never tried restoring this way, but I would use
# xargs aptitude install --schedule-only < thefile
# aptitude install
to restore. The advantage of doing it this way would be to have aptitude 
remember which packages were manually installed and which were 
automatically installed as dependancies after the reinstall.

I have used Henry House's instructions, and I know that his instructions
