Best Practices¶

Sicherheit¶

**Regular-Updates*: System mit Sicherheitspatches aktualisiert halten
** Repository Verification*: Nur vertrauenswürdige Repositories verwenden
GPG Verifikation: Stellen Sie sicher, dass Pakete ordnungsgemäß unterzeichnet werden
Minimale Installation: Nur notwendige Pakete installieren
Sicherheitsaktualisierungen priorisieren Sicherheitsaktualisierungen

Leistung¶

**Fastest Mirror*: Aktivieren Sie schnellste Spiegel Plugin
**Parallel Downloads*: Parallele Downloads konfigurieren
**Delta RPMs*: Delta RPM-Downloads aktivieren
Cache Management: Regelmäßige Cache-Reinigung
** Projektarchiv Prioritäten**: Repository Prioritäten festlegen

Wartung¶

Regular Cleanup: Saubere Paketkassette regelmäßig
**History Tracking*: Transaktionsverlauf überwachen
Abhängige Gesundheit: Überprüfung der gebrochenen Abhängigkeiten
Log Monitoring: Systemprotokolle für Probleme überprüfen
Backup: Wichtige Konfigurationen sichern
