Which is IMO fine - I am terrified of custom address arithmetic that's not really understood by anyone, and very easy to get wrong, with devastating consequences. I spent more or less the whole day stepping assembly in gdb to figure out what exactly is going wrong in that ppc bug. The value proposition of Yocto is still very strong, and is not at all affected by dropping prelink, in my opinion. Alex
