Subject: [PATCH] Update TODO with critical bootable image issues and
 development roadmap

- Add critical issues section for GRUB TTY problems
- Document all attempted TTY bypass solutions
- Organize by development phases with clear priorities
- Add immediate action items and project metrics
- Include risk assessment and integration planning

This update reflects the current blocking issues preventing
functional bootable image creation and outlines the path
forward through bootupd integration.

+# Overseer Project - Debian Boot Architecture Fix Changelog
+
+## 2024-12-19 - Debian Boot Architecture Implementation
+
+### Phase 1: GRUB TTY Fix & Debian Layout Correction
+
+#### Initial Analysis
+- **Problem Identified**: GRUB installation failing with "Error: short-name resolution enforced but cannot prompt without a TTY"
+- **Root Cause**: Container environment cannot provide TTY for GRUB device resolution prompts
+- **Architecture Validation**: Fedora-style partition layout (ESP + Boot + Root) is correct for atomic systems
+- **Partition Scheme**: 3-partition layout confirmed optimal - ESP (FAT32), Boot (ext4), Root (ext4)
+
+#### Implementation Attempts
+
+**Attempt 1: Basic TTY Flag Removal**
+- **Action**: Removed `--tty` flag from podman run commands
+- **Result**: TTY error persisted - flag removal insufficient
+- **Error**: "Error: short-name resolution enforced but cannot prompt without a TTY"
+
+**Attempt 2: Environment Variable Override**
+- **Action**: Added `DEBIAN_FRONTEND=noninteractive`, `GRUB_DISABLE_OS_PROBER=true`
+- **Result**: TTY error persisted - environment variables insufficient
+- **Error**: Same TTY resolution error
+
+**Attempt 3: Comprehensive Non-Interactive Flags**
+- **Action**: Added `--force`, `--no-nvram`, `--skip-fs-probe`, `--no-boot-directory-check`
+- **Result**: TTY error persisted - flag combinations insufficient
+- **Error**: Same TTY resolution error
+
+**Attempt 4: Device Map Creation**
+- **Action**: Created explicit device map `(hd0) /dev/loop0` before GRUB installation
+- **Result**: TTY error persisted - device mapping insufficient
+- **Error**: Same TTY resolution error
+
+**Attempt 5: Alternative GRUB Installation Methods**
+- **Action**: Implemented three fallback methods with minimal flags
+- **Result**: All methods failed with same TTY error
+- **Error**: Same TTY resolution error
+
+**Attempt 6: Explicit Device Specification (Your Suggested Fix)**
+- **Action**: Used `grub-install --target=x86_64-efi --efi-directory=/boot/efi --boot-directory=/boot /dev/loop0`
+- **Result**: Still failed with TTY error - explicit device specification insufficient
+- **Error**: "Error: short-name resolution enforced but cannot prompt without a TTY"
+- **Analysis**: Issue is deeper than device specification - GRUB requires interactive TTY for device resolution regardless of flags
+
+#### What Worked
+
+**Kernel File Copying Pipeline**
+- **Function**: `copyKernelFiles()` successfully copies kernel files from OSTree location to `/boot` partition
+- **Source**: `/usr/lib/ostree-boot/` in container image
+- **Target**: `/mnt/boot/` on separate boot partition
+- **Files Copied**: `vmlinuz-*`, `initrd.img-*`, `config-*`, `System.map-*`
+- **Result**: Kernel files accessible to bootloader in correct location
+
+**Partition Management**
+- **GPT Partition Table**: Successfully created with parted
+- **Filesystem Formatting**: FAT32 (ESP), ext4 (Boot), ext4 (Root)
+- **Mount Point Management**: Correct mounting order and cleanup
+- **Permission Handling**: Fixed OSTree boot directory creation with sudo
+
+**OSTree System Detection**
+- **Detection Logic**: Successfully identifies OSTree components
+- **Components Found**: `usr/lib/ostree-boot`, `usr/lib/systemd`, `usr/bin/bootc`, `usr/bin/bootupd`
+- **Fallback Logic**: Gracefully handles non-OSTree systems
+
+#### What Failed
+
+**GRUB Installation**
+- **UEFI Target**: Failed with exit status 125 (TTY resolution error)
+- **BIOS Target**: Failed with exit status 125 (TTY resolution error)
+- **All Methods**: Failed regardless of flag combinations or environment variables
+- **Root Cause**: Fundamental container environment limitation - GRUB requires interactive TTY for device resolution
+
+**GRUB Configuration Generation**
+- **grub-mkconfig**: Failed with same TTY error
+- **update-grub**: Failed with same TTY error
+- **Result**: No GRUB configuration files generated
+
+#### Final Implementation
+
+**Working Script**: `create-corrected-bootable-image.go`
+- **Language**: Go (compiles successfully)
+- **Partition Layout**: Fedora-style optimal for atomic systems
+- **Kernel File Handling**: Complete pipeline from OSTree to boot partition
+- **Error Handling**: Comprehensive logging and graceful degradation
+- **Fallback Strategy**: Creates minimal bootable image when GRUB fails
+
+**Fallback Behavior**
+- **GRUB Failure**: Detected and logged
+- **Minimal Image**: Created with kernel files and boot instructions
+- **Boot Configuration**: `boot.txt` with manual boot instructions
+- **Result**: Functional image with kernel files, no automatic bootloader
+
+#### Technical Details
+
+**Container Environment Issues**
+- **Podman Version**: Using container image `238208cf481a`
+- **Privilege Level**: `--privileged` with device mounting
+- **TTY Allocation**: Cannot provide interactive TTY for GRUB prompts
+- **Device Resolution**: GRUB cannot resolve device names without user input
+
+**Partition Specifications**
+- **BIOS Boot**: 1MB (unmounted)
+- **EFI System**: 501MB FAT32 mounted at `/boot/efi`
+- **Boot Partition**: 1GB ext4 mounted at `/boot`
+- **Root Partition**: Remaining space ext4 mounted at `/`
+
+**File System Operations**
+- **Copy Method**: `cp -a` for rootfs content
+- **Permission Fix**: `chown -R root:root` after copy
+- **Directory Creation**: `mkdir -p` with sudo for proper ownership
+- **Cleanup**: Reverse mount order unmounting with defer
+
+#### Current Status
+
+**Functional Components**
+- Image creation pipeline: Working
+- Partition management: Working
+- OSTree detection: Working
+- Kernel file copying: Working
+- Error handling: Working
+- Fallback strategy: Working
+
+**Non-Functional Components**
+- GRUB installation: Failed (TTY limitation)
+- GRUB configuration: Failed (TTY limitation)
+- Automatic boot: Not available
+
+**Production Readiness**
+- **Development**: Ready for testing and iteration
+- **Production**: Requires external bootloader or GRUB alternative
+- **Limitation**: Images contain kernel files but no automatic boot mechanism

 # TODO - particle-os: Debian-Native OS Image Builder
 
-## 🎯 **Current Status: REPOSITORY CLEANUP & STRUCTURE ALIGNMENT**
+## 🎯 **Current Status: CRITICAL BOOTABLE IMAGE ISSUES - IMMEDIATE ATTENTION REQUIRED**
 
-**Date**: August 17, 2025  
-**Phase**: Phase 5 - Repository Cleanup & Structure Alignment  
-**Status**: 🧹 **REPOSITORY CLEANUP - Aligning Structure with Original osbuild/bootc-image-builder**
+**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. Now we need to clean up the repository structure to match the original [osbuild/bootc-image-builder](https://github.com/osbuild/bootc-image-builder) repository layout for better maintainability and contributor experience.
+**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.
