# OSTree Filesystem Integration Guide
|
|
|
|
## Overview
|
|
This document combines research on OSTree, atomic filesystems, and live layering for apt-ostree integration.
|
|
|
|
## OSTree Filesystem Research
|
|
|
|
### Core Concepts
|
|
- **Content-addressed storage**: Files identified by content hash
|
|
- **Atomic commits**: All-or-nothing filesystem changes
|
|
- **Deployment management**: Multiple bootable filesystem versions
|
|
- **Rollback support**: Instant reversion to previous state
|
|
|
|
### Key Components
|
|
- **ostree**: Core filesystem management tool
|
|
- **libostree**: OSTree library for programmatic access
|
|
- **ostree-admin**: System administration commands
|
|
- **ostree-repo**: Repository management
|
|
|
|
## Atomic Filesystems
|
|
|
|
### Principles
|
|
- **"From Scratch" Philosophy**: Every change regenerates target filesystem completely
|
|
- **No hysteresis**: State-independent behavior
|
|
- **Reproducible results**: Consistent outcomes
|
|
- **System consistency**: Maintained integrity
|
|
|
|
### Implementation
|
|
- Complete filesystem regeneration
|
|
- Atomic transaction handling
|
|
- Rollback capability
|
|
- State synchronization
|
|
|
|
## Live Layering
|
|
|
|
### Concept
|
|
- **Immutable base**: Base image remains unchanged
|
|
- **Layered packages**: User packages layered on top
|
|
- **Clear separation**: Base vs. user content distinction
|
|
|
|
### Benefits
|
|
- Predictable behavior
|
|
- Easy rollback
|
|
- Consistent deployments
|
|
- Simplified debugging
|
|
|
|
## Integration Strategy
|
|
|
|
### Filesystem Assembly
|
|
- OSTree commit extraction
|
|
- Package layer application
|
|
- Filesystem assembly
|
|
- Boot configuration
|
|
|
|
### Transaction Management
|
|
- Atomic operations
|
|
- Rollback support
|
|
- State tracking
|
|
- Error recovery
|
|
|
|
### Deployment Workflow
|
|
1. Create OSTree commit from base
|
|
2. Apply package layers
|
|
3. Generate deployment
|
|
4. Update bootloader
|
|
5. Activate deployment
|
|
|
|
## Technical Implementation
|
|
|
|
### OSTree Integration
|
|
- Commit creation and management
|
|
- Deployment tracking
|
|
- Rollback implementation
|
|
- Repository management
|
|
|
|
### Package Layer Management
|
|
- Layer creation and application
|
|
- Dependency resolution
|
|
- Conflict handling
|
|
- State synchronization
|
|
|
|
### Boot Integration
|
|
- GRUB/systemd-boot configuration
|
|
- Kernel parameter management
|
|
- Initramfs handling
|
|
- Boot verification
|
