Indeed! I've just reproduced this in an up-to-date sid VM where /tmp is on the ext4 root filesystem. I've purged and reinstalled aufs-dkms to make sure I had a fresh copy built with the current compiler etc. from sid. I've also tried with AppArmor disabled, same result. anonym can reproduce it too, and the bug can be reproduced consistently while booting Tails 3.5 (for testing purposes, one can grab the ISO from http://dl.amnesia.boum.org/tails/stable/tails-amd64-3.5/ and boot it in a VM). Perhaps we should take it upstream and hope the debug trace will ring a bell for them? Cheers, -- intrigeri
