I just inadvertently built a kernel without fakeroot, specifically I said make-kpkg --append-to-version advncdfs --config xconfig kernel_image I don't see any error messages, and the deb was built. My kernel-pkg.conf includes the line root_cmd := fakeroot though I don't find "fakeroot" anywhere in the build log. I also said export PATCH_THE_KERNEL=YES before the build. I thought this was supposed to fail. Has something changed?
