when KERNEL_INSTALL_UKIFY is not supplied we set ukify to $PWD/ukify that will fail (perhaps only for manual installations): FileNotFoundError: [Errno 2] No such file or directory: '/usr/src/linux-6.7-rc1/ukify' this will make sure we have a sane default for UKIFY Signed-off-by: Paymon MARANDI <paymon@utubeipod.xyz>
