## [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
