Unbenutzte Linux Kernel Headers, Images und Modules entfernen
Mit der Zeit landen doch so einige Dateien durch die Kernel Header, Images und Modules auf einem System - um die mittlerweile nicht mehr verwendeten Files zu entfernen kann wie folgt vorgegangen werden:
Anmerkung: sofern rückwirkend Kernel Updates eingespielt wurden, muss auf jeden Fall das System neu gestartet werden!
Getestet auf einem Ubuntu 12.04.4 LTS
