Really nice tutorial. I'd like to note that the swapfile configuration is not great as installed, and it is better to setup a local swapfile (like /swapfile), modify the /etc/fstab, and change the related startup/shutdown scripts in /etc/init.d. I'll see if I can dig up my instructions for this later tonight. This removes the need to use swapfile.7z and makes the function more stable, if you keep your PS2-Linux running for an extended period (like when playing internet radio).
