As regular readers know, we run 32-bit incarnations of distros on the LXF DVD, including 64-bit versions (where available) as extras in ISO image format. Given that most machines made in the last few years are 64-bit, we're thinking of switching over.
For instance, when Ubuntu 9.10 arrives, we can make the DVD boot into the 64-bit version and have the 32-bit edition as an ISO image. In other words, the reverse of before. What do you think?
