## [2025-09-23] - Overlay Filesystem Removal
|
|
|
|
### Removed
|
|
- **Overlay filesystem functionality**: Removed unused overlay filesystem features
|
|
- Removed `OVERLAY_ENABLED` and `OVERLAY_PROTECT_CONFIGS` from configuration
|
|
- Removed `overlayfs` sections from all profile JSON files
|
|
- Removed overlay references from documentation and scripts
|
|
- Added overlay detection and removal functionality for existing mounts
|
|
|
|
### Added
|
|
- **Overlay cleanup functionality**: Added ability to detect and remove overlay mounts
|
|
- `remove_overlays()` function to safely unmount overlay filesystems
|
|
- Automatic cleanup of overlay work/upper directories
|
|
- Removal of overlay entries from /etc/fstab
|
|
- User prompt when overlay mounts are detected
|
|
|
|
### Rationale
|
|
- Overlay filesystems are complex and rarely needed on desktop systems
|
|
- Most users benefit more from tmpfs cache optimization than overlay complexity
|
|
- Simplified codebase by removing unused/incomplete functionality
|
|
|
|
## [2025-09-23] - tmpfs Setup Fix
|
|
|
|
### Fixed
|
|
- **one-button-optimizer.sh**: Fixed critical issue where tmpfs setup was not working
|
|
- Added missing `setup_tmpfs()` function that was referenced but not implemented
|
|
- Enhanced tmpfs analysis to actually scan system for cache directories
|
|
- Added intelligent profile recommendation based on RAM size and existing cache data
|
|
- Fixed tmpfs persistence by generating proper fstab entries
|
|
- Updated systemd service to restore tmpfs mounts after reboot
|
|
|
|
### Enhanced
|
|
- **tmpfs Analysis**: Now scans for actual cacheable data:
|
|
- Browser caches (Chrome, Firefox, Chromium)
|
|
- Package caches (/var/cache/apt)
|
|
- Temporary files
|
|
- Shows actual cache sizes and provides intelligent recommendations
|
|
|
|
### Technical Details
|
|
- **Issue**: When users selected "yes" for tmpfs setup, nothing happened because the `setup_tmpfs` function was missing
|
|
- **Root Cause**: The function was called in main() but never defined
|
|
- **Solution**: Implemented complete tmpfs setup with intelligent sizing and persistence
|
|
|
|
### Testing
|
|
- Added test script (`test-tmpfs-fix.sh`) to verify functionality
|
|
- Confirmed syntax validation passes
|
|
- Verified tmpfs analysis logic works correctly
|
|
|
|
## Previous versions
|
|
- Initial implementation with zram, kernel tuning, and basic tmpfs detection
