install-grub.sh now searches both recipes/core/bootloader/target and local/recipes/core/bootloader/target for the Redox bootloader artifact. The WIP grub recipe (recipes/wip/services/grub) is now a full directory symlink to local/recipes/core/grub instead of just recipe.toml, ensuring COOKBOOK_RECIPE resolves to a directory that contains grub.cfg. This also eliminates the duplicate recipe warning from the cookbook. The GRUB recipe now fails hard (exit 1) if grub.cfg is missing instead of just warning.

# install-grub.sh — Install GRUB bootloader into a Red Bear OS disk image
|
|
#
|
|
# Boot sequence after installation:
|
|
# UEFI firmware → GRUB (menu) → chainload Redox bootloader → kernel → Red Bear OS
|
|
#
|
|
# Usage:
|
|
# ./local/scripts/install-grub.sh <harddrive.img>
|
|
# ./local/scripts/install-grub.sh build/x86_64/harddrive.img
|
|
#
|
|
# Prerequisites:
|
|
# - GRUB recipe built: make r.grub
|
|
# - ESP partition >= 8 MiB (set efi_partition_size = 16 in config)
|
|
# - Python 3 (for fat_tool.py — no mtools needed)
