there really should be a console mode install option during boot for older machines and/or machines with limited RAM. the GUI install is excellent, but part of the beauty of linux is that it can run on minimal hardware compared to the bulkier OSes like windows. at least allow people to easily set up swap space if they have low memory. i have an older laptop (P3 dell, 128 MB) that i wanted to try LM on and it was a huuuuge hassle to install. i had to /etc/init.d/gdm stop before it finished loading, fdisk my drive to make a swap part, enable it, and then load X again to get it going.
come on guys, this is as bad as the vista install disc requirement.
once i got it installed on the hard drive, it ran quite acceptably with a nice big swap partition.
