Use different cache dir for apt-get dist-upgrade

[Ian Patrick Thomas <ipthomas_77@yahoo.com>]

	I am in the process of upgrading my distribution to 2.2 potato? or
whatever is the latest stable.  I have already done an apt-get check and no 
errors were found.  The problem is that I get an error

Sorry, you don't have enough free space in /var/cache/apt/archives/

	I am only using 33% of my /var directory right now, does this file 
need more than 30mb.  If so then is there a way to specify a different file
to use?  Maybe in apt.conf? 

Thanks in advance,

Ian
