Grip mirror with debpartial

[Marcus Osdoba <marcus.osdoba@googlemail.com>]

Hi,
I like to retain load on the public server and improve the speed of 
multistrap by setting up a local grip mirror.
I tried it with the debpartial-config from the web site:
http://www.emdebian.org/grip/debpartial.html
#debpartial-mirror --configfile=./debpartial-mirror-grip.conf update
runs with and greps sid and squeeze package definitions.
But when running upgrade after update I get an error [1]

Did anyone on the list tried to use debpartial as local mirror?
Successfully?

Regards
