notes on upgrading Slackware without burning cd

First I download the iso’s and save to home directory. Open terminal and as root mkdir /psckages. Now I can mount the iso with mount -o loop /home/johnboy/slackware-12.1-install-d1.iso /packages. Now the iso is mounted under /packages. I can now browse the iso contents with Konqueror. Two files of special interest, upgrade.txt and changes and hints.txt. I copy both files to home directory for easy reference during upgrade. Then logout. At prompt enter less upgrade.txt. Follow instructions in upgrade and changes and hints.txt files.
