# restore/YUM/default/950_grub_mkconfig.sh
# 950_grub_mkconfig is a finalisation script (see restore/readme)
# that runs grubby in the target system
# after the files have been restored into the target system
# (i.e. so that GRUB is installed in the target system).
#

# If /sbin/grub-install does not exist on the target system, we don't have grub (legacy)
test -e $TARGET_FS_ROOT/sbin/grub-install || return

# Try to care about possible errors
# see https://github.com/rear/rear/wiki/Coding-Style
set -e -u -o pipefail

# Ensure /proc /sys /dev from the installation system are available in the target system
# which are needed to run grub2-mkconfig in the target system.
# FIXME: If a mount command fails proceed "bona fide" by assuming it is already mounted:
mount -t proc none $TARGET_FS_ROOT/proc || true
mount -t sysfs sys $TARGET_FS_ROOT/sys || true
mount -o bind /dev $TARGET_FS_ROOT/dev || true

# FIXME: This should not be needed here but work via finalize/SUSE_LINUX/i386/170_rebuild_initramfs.sh
# Make initrd verbosely in the target system:
#chroot $TARGET_FS_ROOT /sbin/mkinitrd -v

cp -a $TARGET_FS_ROOT/boot/grub/grub.conf $TARGET_FS_ROOT/boot/grub/grub.conf.bak
# Generate new grub menu entries based on initial entry, which may no longer be valid.
