Hi, The current version 2.17.2-1 of libfakechroot in jessie is unusable with debootstrap (#745082). This may be one of the causes of #809410 too.
You may try debirf with fakechroot and libfakechroot version 2.18-1 from stretch or sid installed. Would it make sense to have version 2.18-1 backported to jessie - or included in a coming jessie point release ? I hope it will help ! Regards, JH Chatenet
