How to prevent automatic deletion of apt cache upon server reboot?

[roman.meier@gismap.ch]

Hi folks,

Especially in the test phase it would really help me if DebianEdu wouldn?t
delete the cache anytime I restart the server.

This causes so much delay since packages have to be downloaded again and
again. Sometimes, our internet connection is really bad.

How can I prevent DebianEdu to do this?

Kind regards,
Roman
