From the comments you clearly know your way around Unix. Is the Debian installer bad because it's bad, or is it bad because it didn't do what you expected? As someone who avoids installing new OSes any more than I have to, I can testify that they all suck to some degree.
The only ones that have been easy have done it by installing everything in the world, which I then spend weeks trying to turn off to get decent performance from my creaky hardware. I once tried to put RedHat on a laptop with a 2G disk. By the time I was deep enough into the custom configs to turn off all the extra crap I didn't need, I might as well not have been using the graphical installer any more.
Once Greg sees this thread I'm sure he'll point you at the graphical installer you should have been using.
