Me neither (yet). I compile the kernel as "ports": hn=$(uname -n) ln=linux-version-as-major-minor objdir=/tmp/linuxobj cp /root/hosts/$hn/linux-$ln.config \ /usr/src/linux-$ln/.$hn-$ln.config || exit 2 chown ports:ports /usr/src/linux-$ln/.$hn-$ln.config || exit 3 [ -x /root/bin/cpupower.sh ] && /root/bin/cpupower.sh hi sudo -u ports sh -c ' ( objdir='$objdir' cd /usr/src/linux-'$ln' || exit 10 if [ -d $objdir ]; then if [ -n "$_cleanup" ]; then ( cd $objdir && make mrproper ) fi else mkdir -p $objdir || exit 1 fi printf -- "-'$hn'\n" > $objdir/localversion-build || exit 3 cp .'$hn-$ln'.config $objdir/.config || exit 2 #sudo -u ports make O=$objdir listnewconfig oldconfig || exit 4 # Documentation/admin-guide/README.rst: "make localmodconfig" #[lsmod>f; LSMOD=f ]make O=$objdir localyesconfig oldconfig || exit 4 nice -n +10 make O=$objdir oldconfig || exit 4 cd $objdir || exit 5 time nice -n +10 make -j`getconf _NPROCESSORS_ONLN` ) 2>&1 ' [ -x /root/bin/cpupower.sh ] && /root/bin/cpupower.sh default followed by (well it is all optional ;) copies as "root": cp $objdir/arch/x86/boot/bzImage $efipart/$hn-$xln-new.efi cp $objdir/System.map $efipart/System.map-$version-$hn ... make modules_install (none, actually) |What exactly are you trying, that fails?

I use efibootmgr: if [ -n "$_efiactive" ]; then if command -v efibootmgr >/dev/null 2>&1 && { efibootmgr | grep -q $hn-$ln-new; }; then bn=`efibootmgr | grep $hn-$ln-new | sed -Ee 's/^Boot([[:digit:]]+).+$/\1/'` efibootmgr -v -n $bn fi fi Well i install the kernel as -new, and boot it once. When booting succeeds with the right kernel, it is moved automatically: { i=1 while :; do ( set -C : > /root/hosts/$hn/.rc-late-hook-$i ) >/dev/null 2>&1 && break i=$((i + 1)) done printf " v=\`uname -r | cut -d- -f1\` if [ \"\$v\" = \"$version\" ]; then if [ "$efipart" != /boot ];then mount $efipart else mount -o remount,rw "$efipart" fi [ -f $efipart/$hn-$xln-new.efi ] && mv -f $efipart/$hn-$xln-new.efi $efipart/$hn-$xln.efi if [ "$efipart" != /boot ]; then umount $efipart else mount -o remount,ro "$efipart" fi exit 0 else echo >&2 'NOT moving kernel on EFI ('$efipart')!' exit 1 fi " > /root/hosts/$hn/.rc-late-hook-$i } Works pretty nice in practice ever since.
