There may be some unneded files or you may still need some files which you deleted. In this tar file I can see for example a file called avahi-daemon, which is a part of additional protocols support package (as far as I remember), so if you didn't have it installed on your device, it's just a waste of space... And if t3hwx9 didn't have some packages installed, which you had installed and which had some files in /etc/event.d, you may still encounter some issues and strange behaviour.
