# TODO - particle-os: Debian-Native OS Image Builder
|
|
|
|
## 🎯 **Current Status: CRITICAL BOOTABLE IMAGE ISSUES - IMMEDIATE ATTENTION REQUIRED**
|
|
|
|
**Date**: December 19, 2024
|
|
**Phase**: Phase 6 - Critical Bootable Image Issues
|
|
**Status**: 🚨 **CRITICAL ISSUES - BLOCKING BOOTABLE IMAGE CREATION**
|
|
|
|
**Summary**: We have a working prototype that demonstrates container-to-bootable-image conversion, but critical issues prevent the creation of functional bootable images. The core problems are GRUB TTY issues, missing kernel files, and bootloader installation failures.
|
|
|
|
**Project Scope**: This project is building a **Debian-native equivalent to bootc-image-builder** that can process **particle-os containers** (which use OSTree + bootc + bootupd) and convert them to bootable disk images, similar to how ublue-os images get processed by bootc-image-builder.

## 🚨 **CRITICAL ISSUES - IMMEDIATE PRIORITY**
|
|
|
|
### **Issue 1: GRUB TTY Installation Failure** 🚨 **BLOCKING**
|
|
- [ ] **Fix GRUB installation TTY prompts in container environment**
|
|
- [ ] **Problem**: `grub-install` fails with "Error: short-name resolution enforced but cannot prompt without a TTY"
|
|
- [ ] **Root Cause**: Container environment lacks proper TTY for GRUB installation
|
|
- [ ] **Attempted Solutions**:
|
|
- [x] Removed `--tty` flag from podman run commands
|
|
- [x] Added environment variables: `DEBIAN_FRONTEND=noninteractive`, `GRUB_DISABLE_OS_PROBER=true`
|
|
- [x] Added GRUB flags: `--force`, `--no-nvram`, `--skip-fs-probe`, `--no-boot-directory-check`
|
|
- [x] Created explicit `device.map` file
|
|
- [x] Implemented multiple fallback `grub-install` methods
|
|
- [x] Used explicit device specification (`/dev/loop0`) in grub-install commands
|
|
- [ ] **Current Status**: All attempts failed - fundamental limitation of container environment
|
|
- [ ] **Next Steps**: Integrate `bootupd` as alternative bootloader solution
|
|
- [ ] **Impact**: **CRITICAL** - Cannot create bootable images without working bootloader
|
|
|
|
### **Issue 2: Missing Kernel Files** 🚨 **BLOCKING**
|
|
- [ ] **Implement kernel file copying from OSTree to boot partition**
|
|
- [ ] **Problem**: Kernel and initramfs files not accessible to GRUB
|
|
- [ ] **Solution**: Copy kernel files from OSTree location to `/boot` partition
|
|
- [ ] **Source Location**: `/usr/lib/ostree-boot` in container image
|
|
- [ ] **Target Location**: `/mnt/boot` on separate boot partition
|
|
- [ ] **File Types**: vmlinuz-*, initrd.img-*, config-*, System.map-*
|
|
- [ ] **Timing**: Must happen before GRUB installation
|
|
- [ ] **Status**: ✅ **IMPLEMENTED** - `copyKernelFiles` function created
|
|
- [ ] **Impact**: **CRITICAL** - GRUB cannot find kernel files to boot
|
|
|
|
### **Issue 3: Bootloader Configuration Generation** 🚨 **BLOCKING**
|
|
- [ ] **Fix GRUB configuration generation**
|
|
- [ ] **Problem**: GRUB configuration not properly generated
|
|
- [ ] **Solution**: Use `grub-mkconfig` to generate proper configuration
|
|
- [ ] **Status**: ✅ **IMPLEMENTED** - `generateGRUBConfig` function created
|
|
- [ ] **Impact**: **CRITICAL** - System cannot boot without proper GRUB configuration
|
