Okay, I am putting together an updated builder image now. So far, I've replaced the kernel with Hijack, and turned on swap during the upgrade. What else needs to be different?

I suppose I can read through Roger's detailed guide and try to find out, but..

Once the final (tested?) version is complete, I'll likely provide the binary on (email) request, and otherwise publish a script to patch an original (copyrighted) builder image.

Cheers
