It depends. Sometimes the bisection can be done in qemu/kvm/xen or similar tools. At least if the problem is not too hardware dependent. And more and more people actually run in such environments. I can also do it faster with autoboot or nfs root/powerswitch, but admittedly that's a very specialized setup most people don't have. Still I agree with your basic point that it should be only last resort. -Andi
