I read in the git repos that live-wrapper is the "next generation' way of generating images. The documentation still seems to be for live-build and I couldn't find live-wrapper docs online. Is live-wrapper going to replace live-build in the future? > If I understand it right, you want a 64bit kernel with a 32bit userland, > correct?

The short answer to your question is 'yes'. I'm designing this boot disk for house-call troubleshooting. I'll normally run the 64-bit operating system but, in the few times I run into old processors, I'll need to run a 32-bit OS. The long answer is 'I'd like both package sets installed so I can choose which to run'. When my auto/config file worked, I believe it was running a 32 userland on top of a 64 kernel when I opted for 64-bit mode. > Bye, > > Andreas > I'm much obliged for your assistance. With thanks,
