I am not totally convinced by this solution. If we adopt it, somebody who installs e.g. octave on an old system-z machine will be hit by a failure in the dpkg installation process, which needs manual intervention. This is likely to generate problems in automated installers (and also confuse and annoy system admins). > the question will be then : does the buildd support these instructions ? I leave that to the s390 porters to answer. -- ⢀⣴⠾⠻⢶⣦⠀ Sébastien Villemot ⣾⠁⢠⠒⠀⣿⡁ Debian Developer ⢿⡄⠘⠷⠚⠋⠀ http://sebastien.villemot.name ⠈⠳⣄⠀⠀⠀⠀ http://www.debian.org
