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,
