Hi all,

for days, I was hunting a nasty bug around multistrap mystically failing in a jessie docker container while working fine in a stretch container as well as a regular jessie VM installation. It turned out that the docker image (debian:jessie-slim) contains

/etc/apt/apt.conf.d/docker-gzip-indexes

which disables the unpacking of packages index files after downloading. Due to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=774698, this also affected the multistrap call of apt-get. So, everyone trying to build Isar images with jessie can run into this bug. Maybe we should
detect the affect version (<2.2.1) and warn at least?

Considering to pull in 2.2.9 from stretch into my builder image now...

We don't use multistrap anymore.
