+Subject: [PATCH] Make installkernel to use kernel-install scripts on BLS
+ configuration
+
+The kernel make install target executes the arch/$ARCH/boot/install.sh
+that in turns executes the distro specific installkernel script. This
+script always uses new-kernel-pkg to install the kernel images.
+
+But on a BootLoaderSpec setup, the kernel-install scripts must be used
+instead. Check if the system uses a BLS setup, and call kernel-install
+add in that case instead of new-kernel-pkg.
