Package: apt
Version: 0.6.46.4-0.1
Severity: wishlist

Currently merely running apt-get update;apt-get update can break for example the mail system, because /var/cache/apt/archives/ keeps growing and growing until a user does apt-get clean.

Specific solution addressing problem:

 There should be an option in a configuration file with a default value of 3GB s.t. the administrator can put a maximum limit on the size of /var/cache/apt/archives/. In case downloading new packages will otherwise go over this bound as set in the configuration file via a Least Recently Used mechanism packages are deleted from the cache and then the upgrading can proceed.
