From: Joerg Jaspert Date: Fri, 20 Feb 2009 23:36:33 +0000 (+0100) Subject: dinstall X-Git-Url: https://git.decadent.org.uk/gitweb/?p=dak.git;a=commitdiff_plain;h=c86d96790c95deed79c5ac3727361ac798c39f0f dinstall commit an initial version of the new dinstall script. People: Please comment. The idea being that we end up with a dinstall that we can interrupt and restart without (too much) trouble.
