portmanager filling /tmp

[Chris Whitehouse]

Hello

portmanager creates a backup package of each port it is about to upgrade 
in case the upgrade fails and stores them in /tmp. Recently a machine 
choked on a large unattended upgrade when /tmp filled up with .tbz's.

I've since changed --with-tempdir=/tmp in the Makefile to point 
somewhere with a bit more space as a workaround (but havne't tested yet).

Is this new behaviour or have I broken something? I'm sure I've done 
similarly large upgrades before without problem.

As a secondary question, man hier(7) says /tmp is for files that may not 
survive a reboot. Can I happily delete anything in /tmp or is there 
stuff I should at least put somewhere else?

The machine is a desktop with various office and multimedia packages 
running  6.2-PRERELEASE #1: Sat Sep 16 12:05:07 BST 2006 i386. Ports are 
up to 20061014.

Thanks for any suggestions

Chris
