I have Red Hat 5.2 installed, and have successfully downloaded the .iso image for 6.1.
How do I use the image to upgrade?
Basically you have to burn that image onto a CDR or CDRW using 'cdrecord'
Then you can boot from the CD media and do your upgrade.
It would be nice if you could just mount the .iso image on a loopback block device and run the upgrade utility from that. However, I don't think you can do that. There's no problem with the mounting part, just use a command like:
mount -o loop /path/to/....iso /mnt/loop
... to mount the .iso file as a filesystem. The problem is that the installer/upgrader for Red Hat is set up to run from the initrd (initial RAM disk) or from the init process. I haven't torn it apart and looked that closely at it --- but it doesn't seem like you can just mount the image, or the CD and run the installer/upgrader. You have to boot from it.
[ Should be pretty easy to boot from one of its floppy images, then point to your loopback mounted drive location as a file source. You might have to mount it at /cdrom in order to convince the diskette to use it. -- Heather ]
