Git Commit: OS-Specific startup.json Generation

Summary

Implement automatic generation of OS-specific default paths in startup.json instead of null values.

Files Modified

Jellyfin.Server/Helpers/StartupHelpers.cs

Method: CreateDefaultStartupConfiguration()

Changes:

• Added OS detection using OperatingSystem.IsWindows(), IsLinux(), IsMacOS()
• Generate platform-appropriate default paths
• Removed confusing "Examples" section with null values
• Added clear comments explaining the configuration
• Improved console output to show which OS defaults were used

Implementation Details

Platform Detection Logic

if (OperatingSystem.IsWindows())
{
    // Windows: C:/ProgramData/jellyfin
}
else if (OperatingSystem.IsLinux())
{
    // Linux: FHS-compliant paths
}
else if (OperatingSystem.IsMacOS())
{
    // macOS: User Library paths
}
else
{
    // Portable: Relative paths
}

Generated Paths

Platform	DataDir	ConfigDir	CacheDir	LogDir
Windows	C:/ProgramData/jellyfin	C:/ProgramData/jellyfin	C:/ProgramData/jellyfin/cache	C:/ProgramData/jellyfin/log
Linux	/var/lib/jellyfin	/etc/jellyfin	/var/cache/jellyfin	/var/log/jellyfin
macOS	~/Library/Application Support/jellyfin	~/Library/Application Support/jellyfin/config	~/Library/Caches/jellyfin	~/Library/Logs/jellyfin
Portable	./data	./config	./cache	./logs

Benefits

1. Immediate Usability - No configuration required for first run
2. Platform Standards - Follows OS conventions (FHS for Linux, ProgramData for Windows)
3. Better UX - Users don't need to research correct paths
4. Clear Documentation - Generated file includes helpful comments
5. Still Customizable - Users can edit paths if needed
6. Backward Compatible - Existing startup.json files are not affected

Testing

Build Status

✅ Solution builds successfully

Test Scenarios

1. Fresh Install (Windows) - Creates startup.json with C:/ProgramData/jellyfin paths
2. Fresh Install (Linux) - Creates startup.json with FHS paths
3. Existing Config - Does not overwrite existing startup.json
4. Custom Paths - User edits are preserved

Related Changes

This builds upon previous work:

• STARTUP_CONFIG_UPDATE.md - Updated startup.default.json with Linux defaults
• Created startup.linux.json and startup.windows.json templates in Resources/Configuration

Documentation

Created:

• OS_SPECIFIC_STARTUP_CONFIG.md - Complete documentation of feature
• STARTUP_CONFIG_COMPARISON.md - Before/after comparison

Console Output

Before

Created default startup configuration at: ./startup.json
You can customize this file to set default paths for Jellyfin.

After (Windows Example)

Created default startup configuration at: E:\Jellyfin\startup.json
Using Windows defaults - using C:/ProgramData/jellyfin
You can customize this file to set different paths for Jellyfin.

Commit Message

feat: Generate OS-specific defaults in startup.json

Instead of creating startup.json with null values, automatically populate
with platform-appropriate default paths:

- Windows: C:/ProgramData/jellyfin
- Linux: FHS-compliant paths (/var/lib, /etc, /var/log)
- macOS: User Library paths
- Unknown/Portable: Relative paths

Benefits:
- Immediate usability without manual configuration
- Follows platform conventions and standards
- Improved user experience for first-time setup
- Clear documentation in generated file
- Still fully customizable

Changes:
- Enhanced CreateDefaultStartupConfiguration() in StartupHelpers.cs
- Added OS detection logic
- Improved console output messages
- Added comprehensive documentation

Fixes: User confusion about what values to use
Closes: Issue with null values in startup.json

Breaking Changes

None - This is a backward-compatible change. Existing startup.json files are not modified.

Future Work

• Add validation to check if paths are writable
• Add interactive path selection wizard
• Add migration tool for moving data between paths
