Control: severity -1 normal With kind help from Wookey, I managed to try dtach in a second arm64 porterbox, also inside an unstable chroot. On turfan.debian.net it works fine.
At the moment I don't understand what important difference there is between these two machines. They are both running variants of 3.16.7 kernels 3.16.7-ckt9-2 on turfan 3.16.7-ckt11-1+deb8u6 on asachi
