[buildd-tools-devel] Bug#802850: Kludge to enable unsharing network in sbuild

[Benjamin Moody]

In case anybody else is interested in doing this, I made the following
hackish patch and it seems to work.  It requires schroot 1.7.0 or
later; I used 1.7.2-3 from experimental, recompiled to run on jessie.

For this to work, you will also need to add a line to the schroot
config file (e.g. /etc/schroot/chroot.d/jessie-amd64-sbuild-xyzzy):
