I wrote a not-so-little wrapper for efibootmgr to pretend grub-install
isn't broken:
# cd /bin
# mv efibootmgr efibootmgr.real
# ln -s efibootmgr.sh efibootmgr
efibootmgr.sh
---
#!/bin/sh
die() {
echo "$*" >&2
exit 1
}
run_device() {
local devdir="$1" label= label_set=
local devname= dev= partition=
shift
if [ "x$1" = "x-L" ]; then
label_set=true
label="$2"
shift 2
fi
devdir="$(cd "$devdir" && pwd -P)"
if [ -s "$devdir/partition" ]; then
read partition < "$devdir/partition"
devname="${devdir##*/}"
devdir="${devdir%/*}"
fi
dev="/dev/${devdir##*/}"
if [ -n "$label_set" -a -z "$label" ]; then
label=$devname
else
[ -n "$label" ] || label="$(lsb_release -si)"
label="$label ($devname)"
fi
set -x
"${0%.sh}.real" "$@" -L "$label" -d "$dev" ${partition:+-p $partition}
}
run_raid() {
local x= argv=
local label= label_set= label_next=
local device= devdir=
local md_level= md_disks=
# extract label
for x; do
if [ "$x" = "-L" ]; then
label_next=true
label_set=
label=

label_next=
label_set=true

else
x=$(echo -n "$x" | sed -e 's|"|\\"|g')

done
